We have gone to a few Birthday parties here. I think it's a great concept. We arrived and the kids and parents gathered in the front room. They go over the rules and then we are all carted to the first room. There are 3 rooms for the kids to go crazy in. the last room is the room where we all eat and sing happy birthday. I am writing this review as a guest so I'm unsure any exact cost involved in the packages. Overall it was great experience. The staff does a great job of keeping an eye on everything. My daughter is still a little too small for some of the bounce slides but she still had a blast. They also seem to keep the whole place pretty clean for have so many kids in and out. I also slid down a few times on the slide with kids.
