When we went in 2009, we stumbled upon a play area near Splash Mountain, as well as a water fountain play area in Epcot. They ended up being some of my kids' favorite moments, as they had a chance to burn off some steam without having to wait in line. So this trip, I want to make sure I know about as many of these spots as possible in each park, so we've got some places ready to hit when they need a little downtime. Can you all please give me some more ideas of places like this? Especially water play areas, but we'll take anything...bonus points if they are near the thrill rides so we can utilize them during rider swap times. Thanks!
