We're going to be in St Louis for most of 1 day this summer. Everything I'm looking at to do closes at 4 or 5. So what is there for the evening? We're not looking to spend a lot of money, just staying occupied while on our way farther west. Also, where is a good part of town to get a hotel? I'd prefer it be on the Kansas City side since that's where we'll be heading the next day. (My kids are 11 & 13 boys if that helps at all!) Thanks!!
