Casino Queen is a good place to stay if you want to visit the Cardinals Stadium (great tour) and the Arch or anything else downtown. Do not worry that it is located in East St Louis. They have excellent security and will even pick you up to/from the Metro which we rode during the day with no issues. If you have a big rig, parking is really just a big parking lot with hook ups. If you want to go to a Cardinals game, they provide a free shuttle that picks you up/drops you off for the game. We did not go to the casino while there. We go around St Louis when just going through the area via I270 to I255.
