Ameristar Casino Resort St Charles is a casino hotel beside the Missouri River in St. Charles, Missouri, in the greater St. Louis area. Its strongest reason to visit is the overnight package: 397 suites, sit-down dining, a spa, and gambling without driving between them. I think it makes more sense as an adult getaway than simply a place to squeeze in a few spins. The main trade-off is that resort amenities have separate schedules and costs, particularly the seasonal pool, spa treatments, and cabana rentals.

What kind of casino is Ameristar St. Charles?
Ameristar is a regional casino resort whose suites, restaurants, spa, and event spaces give visitors reasons to stay beyond the gambling. That matters for couples or groups whose enthusiasm for the casino is not equally shared.
This is St. Charles, not downtown St. Louis. Historic St. Charles offers an alternative to spending the entire getaway inside the resort, but I would not choose Ameristar primarily as a base for downtown St. Louis sightseeing.
The Missouri Gaming Commission lists the property at One Ameristar Boulevard, with the information number shown above. For other destinations around the state, see our Missouri casino guide.
Casino games, slots, and video poker
The casino combines slots and video poker with live table games. I would not build a visit around a promised low minimum or a particular machine title: inventories, table availability, and betting limits change. If one game is the reason you are coming, call and ask about that game specifically.
Slots and video poker
Look at a machine’s actual wager and rules, not simply its denomination. A penny slot can require a much larger bet than its name suggests, particularly with feature wagers.
For video poker, inspect the pay table before playing. Two machines with the same game name can offer different payouts. Neither a jackpot display nor somebody else’s losing session tells you what value a machine offers.
My advice is to set your gambling budget before sitting down. Rewards and promotions are extras, not reasons to keep feeding a machine after that budget is gone.
Table games
Blackjack, craps, roulette, and poker-based house games provide alternatives to the machines. Read the posted rules and limits before buying in, particularly the blackjack payout and any optional side bets.
A low minimum is only the starting point. Several side bets can turn a modest wager into a considerably more expensive round. Ask about available limits, and remember that an individual table’s schedule may differ from the casino’s general hours.
Poker room
Ameristar St. Charles has no dedicated player-versus-player poker room. Video poker and poker-themed table games are different products, not substitutes for a cash-game room.
Sportsbook
The property has no on-property retail sportsbook. Amerisports offers sports viewing, but a big screen and a betting counter are not the same amenity.
Hotel suites: the strongest reason to stay
The hotel’s official wedding and amenities brochure lists 397 suites and describes accommodations of approximately 650 square feet, with sunken living rooms and floor-to-ceiling windows overlooking the Missouri River or St. Charles. That size is a published description, not a guarantee for every room category.
The brochure also lists double vanities, separate tubs and showers, and in-room safes. Those are useful distinctions from a basic overnight room, especially when two people are getting ready for dinner or an event.
The official property overview says the hotel rooms were fully renovated in December 2024, a useful distinction when reading reviews of older stays.
For me, the comparison is not simply Ameristar versus the cheapest nearby hotel. It is the complete cost of staying on-site versus a separate hotel, transportation, and the inconvenience of moving between venues. Staying upstairs has a practical advantage after an evening involving drinks, but that convenience still needs to fit your budget.
Compare final reservation totals, including taxes and any mandatory charges. Confirm the bed arrangement, cancellation deadline, incidental deposit, and accessibility requirements before booking.
Seasonal pool and ara spa
The brochure describes a seasonal indoor-outdoor pool with fountains, a fire pit, and whirlpools. Summer cabanas are available to rent. Do not interpret “indoor-outdoor” as a promise of year-round swimming: check availability for your dates before booking a pool-focused getaway.
Ara spa lists massages, facials, nail services, a sauna, a hot tub, and a steam room. These give a nongambling companion something more substantial to do than wait for dinner. Ask which facilities accompany a treatment, what requires an appointment, and what costs extra.
Restaurants and bars
Two options illustrate the dining range:
- Bugatti’s Steak & Pasta: The sit-down dinner choice, serving steaks, Italian dishes, and seafood. The brochure describes a private 22-seat dining room available by request for celebrations or smaller group meals.
- Amerisports Bar & Grill: The casual sports-viewing option, with a 34-foot video wall and two Topgolf Swing Suites.
I would reserve a special-occasion dinner rather than leave it to chance. Check restaurant opening days and kitchen closing times separately from casino hours, particularly if you expect to eat late.
For a longer stay, a meal in historic St. Charles can break up the resort routine. Keeping every meal on-site is convenient, not compulsory.
Entertainment and private events
The Topgolf Swing Suites add an activity beyond watching sports. Confirm reservations, availability, and pricing before counting on a simulator session.
Ameristar also has ballrooms and event spaces, including RYSE and Bottleneck Blues Bar. An event-space listing is not a nightly entertainment schedule, so check what is happening during your stay.
Private-event costs: look beyond the menu price
For weddings and private celebrations, the menu subtotal is not the finished bill. The brochure publishes a 24% taxable service charge and an 11.035% sales tax for event food and beverage, including tax on the service charge. These are private-event terms, not a statement about ordinary restaurant checks.
On an illustrative $2,000.00 food-and-beverage subtotal, the 24% service charge alone adds $480.00 before tax. Compare inclusive written proposals rather than menu prices.
Minimum spending matters, too. Under the published policy, a shortfall becomes a rental charge. With an illustrative $5,000.00 contracted minimum and $4,000.00 in qualifying spending, the difference becomes $1,000.00 in rental, also subject to tax and service charge. Ordering less does not necessarily make the event cheaper.
Parking and practical visit information
Complimentary self-parking in two covered garages is a useful advantage for overnight guests and event visitors. Ask about valet arrangements separately rather than assuming the same terms apply.
Confirm which garage and entrance best serve your destination. Hotel check-in, dinner, and a ballroom event may call for different arrival plans. Visitors with mobility needs should ask about the shortest suitable route and specific room features.
You must be at least 21 to gamble. Bring valid government-issued photo identification, and arrange a sober ride if you are not staying overnight.
Before booking, confirm smoking arrangements, pool access, and transportation needs. If smoke exposure is a deciding factor, ask about both your room and the shared areas you will use, not just whether a nonsmoking room is available.
Boyd Rewards
Ameristar St. Charles participates in Boyd Rewards. Use your account for eligible play, and ask how table play is rated before assuming it is being tracked.
I regard casino rewards as a rebate on entertainment already planned, not a shopping list. A room offer or dining credit stops being a bargain if earning it persuades you to gamble beyond your budget.
Who should choose Ameristar St. Charles?
I would put Ameristar on the shortlist for couples, overnight casino visitors, and event groups who value a spacious suite, covered self-parking, and dinner without another drive. Its spa, sports-viewing setup, and seasonal pool give companions alternatives to gambling, although treatments and cabanas need their own budget. Choose a simpler hotel if you will barely use those amenities, or a downtown St. Louis property if city sightseeing matters more than a St. Charles casino getaway.
