Monkey Joe's is an inflatable play center. It looks like they have your typical slides and bounce houses. I will say they have a pretty sweet-looking parent lounge! They do recommend supervising your children at all times, but I am assuming if your kiddos are a bit older and able to do the run around-check in thing, it would be a nice place to chill.
