We are going to do that next month for my babies 5 th b'day. Im going to have them do it. Here in Texas you get a 2 hr party and lots of entertainment and goodies for the kids. We are estimated at paying around 300 and that's cheaper than a house party would cost us ( food, drinks, beer, jumping house and decorations)
Plus, I don't have to clean it up or entertain them! My baby gets to be the center of attention and she loves that place! Win win in my book!
