I agree with the previous posts about a disorganized sign in. If you have pre-paid for a time slot, get there early! Not quite sure what the issues are there - perhaps too many fields to enter on a computer screen. Maybe there's a learning curve for the staff.
I took a 3 year old and two 5 year olds. I was disappointed that the kiddie area was not open yet (website didn't say that). Luckily my 3-yr-old is fearless and was not intimidated by the teenagers. I also jumped with her.
I thought it was great fun, both for my kids and myself. We enjoyed watching the older kids who can do more tricks. I plan to take my husband back as this is right up his alley. I've been calling this place Monkey Joe's for teenagers. It's expensive, but do-able for once-in-a-while activity.
Tips: We went one afternoon during school vacation. It was crowded, but not insane. We had a 4:00 jump time (did not pre-register online) but they weren't really checking times, so we got to jump for more than an hour.
You can wear shoes or go barefoot, but no socks (too slippery I guess).
There is currently nowhere to hang bags or coats. People lined them up on the floor.
Wear short-sleeves - it was a mild humid day and we were really hot.
