My husband, I and our 3 kids (4, 7 and 9) will be in St. Louis for 3 nights April 22-25. We plan to see City Museum, the Zoo, the Arch and the Budweiser Brewery. (I'm so bummed Grant's Farm is only open on the weekends at that time.) We'd like to stay in a hotel that's family friendly and has a nice swimming pool. We'll have a car, so we don't need to stay super close to the attractions, but for convenience sake, we don't want to be too far out. The main thing, though, is that it have a nice indoor swimming pool. Any suggestions? Thanks in advance for your input!
