South Dakota hotel prices currently vary enough that one statewide number can be misleading. As of September 7, 2026, KAYAK reports an average double-room price of about $155, while HotelsCombined’s September 2 snapshot reports an average near $139 per night. Using roughly $140–$155 as a statewide planning band is more useful than relying on one exact figure. Rates around the Black Hills and Mount Rushmore can rise sharply in summer and during major events.

How we use hotel-price data: Different websites can report different “average” prices because they use different properties, room types, travel dates, booking windows, and calculation methods. This guide cross-checks live hotel-search data, sampled hotel datasets, official South Dakota tax guidance, tourism sources, and individual hotel policies. A low deal price is not treated as the statewide average.
What Are Current South Dakota Hotel Prices by Accommodation Type?
There is no single universal South Dakota hotel average. KAYAK’s South Dakota hotel data currently reports an average double-room price near $155. HotelsCombined reported an average near $139 per night in its September 2, 2026 snapshot.
A separate Budget Your Trip analysis of 446 South Dakota hotels reports an overall average near $171 and a median near $138. Its category-level data provide a useful way to compare hotel types:
- Budget hotels: About $91 per night on average in the sampled dataset, with a median near $93.
- Mid-range hotels: About $166 per night on average, with a median near $152.
- Luxury hotels: About $433 per night on average, with a median near $405.
These figures are planning benchmarks, not guaranteed quotes. A basic roadside room can exceed a category average on a sold-out weekend, while an upscale hotel can fall below its usual range when discounted.
If you are comparing hotels with resorts, see the separate guide to the average resort cost per night in South Dakota.
Hotel star ratings are not perfectly consistent across booking platforms. Compare the actual room, location, guest reviews, cancellation policy, parking, breakfast, and included amenities instead of relying on the star label alone.
A hotel average is a planning benchmark, not a quote. The data source, travel date, city, room type, and remaining inventory can move the number substantially.

What Are the Seasonal Trends That Affect South Dakota Hotel Costs?
South Dakota hotel rates change throughout the year. Summer vacations, weekend stays, school breaks, holiday travel, and major events can all increase demand.
- December: KAYAK’s current statewide average is about $112, making December the lowest-priced month in the latest dataset.
- August: The current KAYAK average is about $172, making August the most expensive month in its current statewide data.
- Black Hills summer: Hotels near Mount Rushmore, Keystone, Custer, Deadwood, Rapid City, and Sturgis can become much more expensive as visitor demand rises.
- Special events: The Sturgis Motorcycle Rally, holiday celebrations, sports tournaments, conventions, and local festivals can override normal statewide seasonal patterns.
Travel South Dakota says Mount Rushmore-area hotel rates can start around $50 but rise significantly during summer and large events. Travelers seeking lower rates should compare late-fall, winter, and early-spring dates while checking weather conditions and seasonal attraction hours.
Event Surge Alert: During the Sturgis Motorcycle Rally, lodging can run roughly three to five times normal rates, and many accommodations require multi-night stays that can extend from three to seven nights. If your Rally dates are fixed, begin searching many months earlier than the normal statewide booking window. See the dedicated guide to hotel prices during the Sturgis Rally in South Dakota.
Note: Statewide monthly averages combine many cities and hotel types. A December hotel in Sioux Falls and a Black Hills property during a special event can have completely different prices.
Which Days of the Week Offer the Lowest Hotel Rates?
Current KAYAK statewide data shows that Sunday is the lowest-priced stay day, averaging about $142 per night. Saturday is currently the highest, averaging about $188.
These numbers describe the night of the hotel stay. They do not prove that clicking the booking button on Sunday will always produce the lowest rate. Hotel prices change with occupancy forecasts, local demand, remaining inventory, and cancellation activity.
Lowest Rates by Stay Day
- Sunday: Current KAYAK average near $142.
- Weeknights: May offer better value in leisure destinations after weekend visitors leave, although local events can reverse the pattern.
- Saturday: Current KAYAK average near $188 and the highest-priced stay day in the current statewide dataset.
- Event dates: Can override normal weekday patterns, especially in the Black Hills.
When Should You Book to Secure the Best Rates?
KAYAK’s current statewide guidance recommends booking at least 7 days before arrival. Treat that as a general market benchmark rather than a rule for every trip.
Summer vacations, Mount Rushmore visits, holiday weekends, and trips tied to fixed events can justify booking much earlier. The Sturgis Motorcycle Rally is an extreme example because high demand and minimum-stay rules can reduce normal last-minute flexibility.
Advance booking is not a guarantee of the lowest possible rate. Hotels may lower prices later when rooms remain unsold or raise them when demand strengthens. A flexible or refundable reservation lets you secure a room and recheck the price later.
Pro Tip: After booking a refundable rate, check the same hotel, room type, occupancy, and cancellation terms periodically. Rebook only when the new complete stay total is lower and the included benefits are equivalent.
How to Find Affordable Hotels in South Dakota
You can improve your chances of finding a good hotel rate by comparing more than the first nightly price shown in search results.
- Start with the current market: KAYAK’s general benchmark is at least 7 days ahead, but begin much earlier for fixed Black Hills events.
- Check nearby dates: Moving the stay by one day can avoid a high-demand Saturday or local event.
- Compare nearby towns: A longer drive can be worthwhile when Keystone, Deadwood, or central Rapid City is unusually expensive.
- Match the same room: Confirm bed type, occupancy, breakfast, parking, cancellation rules, and taxes before comparing prices.
- Use total-price filters: Compare the complete mandatory lodging price rather than a lower headline figure.
- Look for useful inclusions: Free breakfast, free parking, a refrigerator, or a kitchenette can reduce other trip expenses.
- Compare other lodging types: Cabins, vacation rentals, campgrounds, and resorts can be worth checking when hotel inventory is tight.
- Set price alerts: Track several acceptable hotels instead of relying on one property.
- Read recent reviews: A low rate has little value if cleanliness, noise, maintenance, or location problems make the stay unsuitable.
Warning: A nonrefundable room can become the most expensive choice if your plans change. Read the cancellation deadline, time zone, prepayment terms, and penalty before booking.
Hotel Cost Planning by Major South Dakota Destination
Current KAYAK hotel-search shares place Rapid City first at about 38%, followed by Sioux Falls at 34%, Deadwood at 20%, and Keystone at 8%. These percentages describe destination popularity within KAYAK’s South Dakota searches, not hotel-price shares.
City-by-City Planning Snapshot
| Destination | Current KAYAK Search Share | Main Price Pressure | Best Travel Purpose |
|---|---|---|---|
| Rapid City | About 38% | Black Hills summer travel, conventions, sports, and Sturgis spillover | Central base for Black Hills day trips, dining, and airport access. |
| Sioux Falls | About 34% | Business travel, conventions, concerts, sports, and weekend events | Business travel, road-trip stopovers, and Falls Park visits. |
| Deadwood | About 20% | Summer tourism, entertainment events, and Sturgis Rally demand | Historic gaming, nightlife, and northern Black Hills exploration. |
| Keystone | About 8% | Strong Mount Rushmore seasonality and limited winter inventory | Closest proximity to Mount Rushmore National Memorial. |
Rapid City often works best for travelers who want flexibility and a central base. Keystone is better when reducing the drive to Mount Rushmore matters most. Deadwood suits visitors focused on history and entertainment, while Sioux Falls is a stronger choice for eastern South Dakota and cross-state road trips.
Exact city rates should always be checked for your dates. Travel South Dakota notes that Mount Rushmore-area prices can begin around $50 but climb significantly during summer and large events, which is why one statewide average should not be treated as a Black Hills summer quote.
Sample Room Budgets
Using the current $139–$155 statewide planning band from HotelsCombined and KAYAK, room-only costs before government taxes and optional trip expenses would be approximately:
- One night: About $139–$155.
- Two nights: About $278–$310.
- Three nights: About $417–$465.
These examples do not include government taxes, meals, fuel, attraction tickets, optional parking, or pet charges. A discounted room can lower the total, while a summer weekend or major event can push it well above the statewide planning range.
How Do South Dakota Hotel Taxes and Municipal Fees Work?
The advertised lodging price and the final amount charged to your card may differ because government taxes and optional services can be added. According to the South Dakota Department of Revenue’s June 2026 lodging guidance, transient lodging can be subject to several tax layers:
- State sales tax: 4.2%.
- Tourism tax: 1.5%.
- Municipal sales tax: 1% to 2% where imposed.
- Municipal gross receipts tax: An additional 1% on lodging where the municipality imposes it.
- Local occupancy or BID assessments: Separate flat lodging assessments can apply to particular properties or business-improvement districts.
The easiest way to understand the percentage tax is as a ladder. State sales tax plus tourism tax equals 5.7%. A 1%–2% municipal sales tax can raise the percentage to 6.7%–7.7%. Where a 1% municipal gross receipts tax also applies, the percentage can reach 7.7%–8.7%.
Flat occupancy assessments are separate. For example, the City of Deadwood currently provides a BID #9 remittance form showing a $2 occupancy tax per applicable occupied room. Property coverage can differ, so use the taxes and assessments shown for your actual hotel rather than assuming every South Dakota property has the same final rate.
For a simple planning example, a $150 displayed room total subject to an 8.7% combined percentage tax plus a $2 local occupancy assessment would cost about $165.05 for one night. Three nights would rise from $450 to about $495.15 before optional services.
South Dakota also treats several lodging-related charges as taxable in applicable situations, including resort fees, pet fees, cancellation fees, no-show fees, rollaway-bed charges, and forfeited deposits.
The FTC’s Rule on Unfair or Deceptive Fees generally requires calculable mandatory lodging fees to be included in the total price displayed upfront. Government taxes may be excluded from that first total, but the seller must disclose excluded charges and show the final amount before asking for payment.
Warning: Compare the final amount for the full stay, not a crossed-out rate or a nightly figure shown without government taxes. Also check optional parking, pet, breakfast, and deposit terms.

Which Hotel Amenities Deliver the Best Value in 2026?
Focus on amenities that improve the trip or lower your total out-of-pocket spending:
- Cost-Saving Inclusions: Free breakfast and free parking can materially reduce a road-trip budget. Parking is not always included; for example, Canopy by Hilton Sioux Falls Downtown currently lists self-parking at $20 per day.
- In-Room Convenience: A mini-fridge, microwave, or kitchenette can reduce dining costs during longer stays.
- Family Amenities: Look for indoor pools, crib availability, and connecting rooms when traveling with children.
- Pet Policies: Verify whether the charge is nightly or per stay. Canopy by Hilton Sioux Falls Downtown, for example, currently lists a $75 nonrefundable pet fee per stay.
- Accessibility Needs: Confirm the specific feature you need directly with the property because accessible-room labels can cover different layouts and equipment.
Is It Better to Book Direct or Through Third-Party Sites?
Compare the hotel’s official website with at least one reputable booking platform. Use the same travel dates, room type, number of guests, bed choice, cancellation terms, and included amenities.
- Direct booking: May provide easier communication, loyalty benefits, room-selection features, or simpler changes when the hotel controls the reservation.
- Third-party booking: Can make it easier to compare many properties and may offer promotional or bundled rates.
- Package booking: May reduce a combined flight, car, and hotel total, but individual prices and cancellation terms can be harder to compare.
- Pay-now rate: Can cost less but usually has stricter cancellation terms.
- Pay-later rate: Often costs more but can provide additional flexibility.
Save the confirmation email and take a screenshot of the room description, included benefits, cancellation deadline, and final total. This gives you a record if the booking details later appear differently.
Smart Ways to Make Your Travel Budget Go Further in South Dakota
- Use $140–$155 as a current statewide starting band: Adjust upward for high-demand Black Hills dates and downward when you find a genuine low-season deal.
- Check Sunday stays: Sunday currently has the lowest KAYAK statewide stay-day average near $142.
- Consider December: It currently has KAYAK’s lowest monthly statewide average near $112.
- Reserve earlier for fixed events: KAYAK’s normal benchmark is at least 7 days, but major events can require months of advance planning.
- Compare nearby towns: Balance a cheaper room against added fuel, parking, and driving time.
- Choose refundable terms when practical: This lets you recheck rates without immediately giving up the original reservation.
- Calculate the full trip: Include government taxes, optional parking, meals, pet charges, fuel, and attraction costs.
- Check eligible discounts: Compare legitimate AAA, senior, military, employer, government, and hotel-loyalty rates when applicable.
Note: Hotel averages update frequently. Always verify the room price, government taxes, mandatory lodging total, optional services, and cancellation policy for your exact dates before paying.
Frequently Asked Questions
How much does a trip to South Dakota cost?
For lodging alone, the current statewide $139–$155 planning band would put three nights at roughly $417–$465 before government taxes and optional trip costs. Your complete South Dakota trip will also depend on transportation, meals, attractions, fuel, parking, and destination.
What is the best hotel in Sioux Falls, South Dakota?
There is no single best hotel for every traveler. Canopy by Hilton Sioux Falls Downtown is one modern option next to Falls Park and the Steel District. Its official page currently lists $20 daily self-parking and a $75 nonrefundable pet fee per stay. Compare its room rate, amenities, location, and cancellation terms with other downtown and interstate-area hotels.
What happened to the $150 hotel room?
A $150 room remains a realistic South Dakota benchmark. Current major datasets place statewide averages around $139 to $155, although summer Black Hills demand, Saturday stays, special events, premium locations, taxes, and optional services can move the final cost well above $150.
What is the cheapest month to book a South Dakota hotel?
KAYAK currently shows December as the lowest-priced month, averaging about $112 per night. January is also part of the lower season, but weather, holiday dates, and seasonal attraction closures should be considered.
Should you stay in Rapid City or Keystone for Mount Rushmore?
Choose Keystone when staying close to Mount Rushmore is your top priority. Choose Rapid City when you want a larger selection of hotels, restaurants, shopping, airport access, and a central base for several Black Hills day trips.
Are South Dakota hotel taxes included in the advertised price?
Not necessarily. Under the FTC fee rule, calculable mandatory hotel fees generally must be included in the upfront total price, but government taxes may initially be excluded. Before payment, the seller must disclose the excluded charges and display the final amount you will pay.
How far ahead should you book a South Dakota hotel?
KAYAK’s current statewide guidance recommends booking at least 7 days before arrival. Start much earlier for the Sturgis Motorcycle Rally, peak Black Hills summer dates, major holidays, and other fixed high-demand events.
Why do South Dakota hotel averages differ by website?
Hotel websites can use different properties, travel dates, room categories, booking windows, and calculation methods. A live-search average can therefore differ from a dataset built from hundreds of properties. A recent low deal is different again: it shows what one room may be available for, not what the typical South Dakota hotel costs.
Conclusion
Current South Dakota hotel data supports a practical statewide planning band of roughly $140–$155 per night rather than one fixed average. KAYAK currently places December near $112, August near $172, Sunday near $142, and Saturday near $188.
Your actual rate can move far above or below those benchmarks. Black Hills summer demand and the Sturgis Motorcycle Rally can create especially large increases, while lower-demand winter dates may cost much less.
Before booking, compare the complete stay total, government taxes, local assessments, optional parking or pet charges, room details, and cancellation terms. Then check the same room on nearby dates or at nearby towns before committing.
