Down side: too expensive and if you have socks that don't have rubber grips on them, you have to buy a pair of their over-priced socks. Kind of a racket? Also, it's really dark inside which isn't exactly a cheerful place to hang out. Up side: the place has been practically empty every time we've been there, so there is plenty of space to jump, and parking is never a problem. I think it was more popular when it was Jump City, but most of the kids we know have found a place they like a lot more in Mesa, that has everything from trampolines to skateboarding, etc.
