Was in St Louis visiting colleges and decided to try the Ameristar for one night. Have been to Vegas many times along with a few non-LV casinos and I was pleasantly surprised at the Ameristar St Charles.
First of all, the hotel itself was really top notch. I had a Deluxe King Suite and it was surprisingly spacious, clean, nice bathroom amenities, two TVs. It was not very crowded so check in took no longer than 5 mins, bed was comfortable. Did not have much more interaction with staff but seemed courteous enough.
The casino itself was ok, Smoking always a problem but that's just how casinos are. Was glad to see there were more than just one or two crap tables since that is what I play mostly. Of course they try to replicate the Vegas casino feel but the attempts fall short without the size and scale of the Wynn, Bellagio, MGM etc. The dealers were all polite, efficient and friendly which is important for the overall gaming experience. For a local casino I was decently pleased overall and would probably stay here again if in the area.
