A Refined Waterfront Sanctuary in Greater St. Louis
Situated on the banks of the scenic Missouri River in historic St. Charles, Ameristar Casino Resort Spa provides a comprehensive hospitality destination mere minutes from Lambert-St. Louis International Airport. The resort eliminates the common pain points of standard urban casino hotels, replacing crowded corridors and noisy guest quarters with a quiet 397-suite residential wing isolated from the active entertainment areas.
Each suite features sunken living rooms, plush king or queen pillow-top bedding, and expansive glass windows framing either tranquil river waters or the historic town skyline. Culinary offerings range from prime aged beef and handcrafted Italian classics at Bugatti's Steak & Pasta to craft brews and oversized burgers at Amerisports Bar & Grill, allowing guests to transition seamlessly between celebrations and focused leisure.
The Ara Spa & Wellness Sanctuary
Covering 7,000 square feet, the on-site Ara Spa provides six custom treatment suites, eucalyptus steam chambers, private hydrotherapy whirlpools, and relaxation lounges. Expert therapists combine restorative botanical wraps with heated stone massages, providing hotel guests a peaceful antidote to the excitement of the gaming tables downstairs.
