Yes, they post a schedule on a chalk board in front of where you go into the food court, etc. building. My kids really enjoyed several of the activities. They especially enjoyed the Pop Parade where they got to parade from the food court past the check-in lines and back while playing provided musical instruments. We did the parade three times and the participants all got certificates and small prizes (stampers, rings, slap bracelets.) The parade was every evening around 5:30. They also got buttons for doing the Twist. It was really fun and DD6 is INSISTING we stay at Pop again next trip so she can do the parade again.
I know for sure they allow arm floats and small rings and water balls. I'm not sure about noodles or any larger floats. Have fun!
