As the first AAA Four Diamond hotel in St. Charles, Ameristar's 397-room all-suite hotel brings state-of-the-art amenities to the St. Charles riverfront. The hotel pays homage to the historical architecture of the area. The hotel includes an outstanding selection of first-class in-suite amenities; an impressive indoor/outdoor pool including a distinctive landscape area; a tranquil and luxurious full-service spa and a new 2,350 space car parking garage, (increasing the total number of available spaces in the two parking garages to 6,100). The distinctive design of the hotel and garage exterior was inspired by the architectural characteristics of the preserved buildings of St. Charles' historic Main Street and the newly-refurbished warehouse buildings of downtown St. Louis' Loft District. The grand hotel tower is painstakingly detailed to incorporate the time-worn quality of aged brick and decorative ornamental cast moldings indigenous to the historic structures of the area. Guestroom windows mirror the reflective glow of night lights dancing across the nearby river.Two ballrooms, five meeting rooms and an executive board room are included in the 19,200 square feet of meeting space. High-end finishes, rich wood panels, exclusively-designed woven carpet and custom lighting define the contemporary look of the center. A state-of-the-art business center and a fully-equipped banquet kitchen complete the spectacular facility, which is housed in the second level of Ameristar's existing $360 million casino entertainment facility.
