We are currently staying at Casino Queen. The campground is not fancy, just really a black topped parking lot with hook ups. There are two sections, the smaller sites have a few trees, the large sites are out in the open. The campground is close to the interstate and there is lots of train traffic. However, the trains are moving very slowly so once the engines are past, the noise it really not noticeable. There is a really nice grassy area with covered picnic tables and a children's play area and there were some kids out there playing. The staff is super friendly and helpful. We drove to the zoo. Parking is $15 and they take credit cards for the parking. It backs up traffic terribly with all those long credit card transactions. We took the Metro Link to Busch Stadium for a tour, one of the best $10 we spent (per person) and we also took the Metro Link to the Arch. We did not feel unsafe in any way. The Casino has a free shuttle to take you to/from the game. You can call or flag down Security from the campground and they will pick you up and take you to the Metro Link station or the Casino. The advertised mini mart for the campground sells mostly alcohol. Just follow the directions carefully and you will not have trouble finding the Casino. The state park is fine but is is far away from the attractions you will want to visit and parking is pretty darned expensive. We will stay here the next time we want to see a Cardinals game.
