About Ameristar Casino Resort and Spa, St. Charles

Riverside casino resort with indoor/outdoor pool and spa

On the Missouri River

Ameristar Casino Resort and Spa is in St. Charles, right off the I-70 freeway on the Missouri River. Frontier Park on the river is a 10-minute walk north, St. Charles Convention Center is a 5-minute drive west, and the center of St. Louis is a 25-minute drive southeast.

Near history and concerts

If you drive 5 minutes north you'll reach the interesting historic site of the Shrine of St. Philippine Duchesne, the first free school west of the Mississippi. If music is more your thing, you can hear concerts a 7-minute drive southeast, at Verizon Wireless Amphitheater.

Huge casino, 12 bars

You'll hit the jackpot when it comes to service, with free valet parking, 24-hour fitness room, 7 restaurants, a 24-hour business center, a 1950s-style martini bar, and a huge casino. You can get a sunny or shaded swim and soak in the indoor/outdoor pool and hot tub, and then visit the day spa.

Extra living space

The 397 lavish guestrooms feature big bathrooms, sunken living areas, and floor-to-ceiling windows with views of the river or city of St. Charles. You get a choice of flat-screen TVs, and rooms also have mini-fridges, coffeemakers, free bottled water, and free WiFi.
Please note: The pool will be closed to guests under 21 years old every Sunday through September 6

Stayed a week for My 25Th Birthday :)
Very nice hotel, Love the valet, PLENTY TO EAT ☺ & plenty to see. Only Complaint would be with the casino. I honestly didn't notice anybody winning much the whole week. I stayed in a few other Casino prior to this trip and they were all different but NOBODY hit on the Ameristar In my honest opinion. I'll be back for sure though.

Worst night ever
TV was slow to get channel's, and did not receive channels at all past 1000 01/31 Had loud party in room next to mime at 11pm until after 230 AM,called front desk at midnight but the noise continued. Ruined a nights sleep. I've had wonderful syaus at Amristar but this last visit will weigh heavily on my decision to stay again.
