Sounds like fun. There is the Jumping in Loveland as well. Whenever I have my boy and his cousins (two other four year olds), I load them up on sugary apple juice and let them loose in Jumping. About an hour and a half later, the sugar crash hits at the same time as the physical exhaustion, and they all go right to sleep for an hour or two. That said, I'd be willing to travel an hour or so for a play date. I can bring a four year old and some baked goods. I'm also good at holding other people's kids, as long as I get to give them back.
