This Ameristar Casino Resort Spa in St Charles, Mo is one of the best facilities we have stayed in for years. The rooms are absolutely remarkable with sunken livingroom and large bathroom. The rooms are beautifully decorated and well kept up. The resort offers a full spa, exercise room, hot tubs and pools both inside and outdoors. Room service was quick, reasonably priced and the food was remarkably wonderful. If you are in the St Louis Mo area this is the place to stay. Also the casino is full and exciting to play in.
