We had my grandchildren's birthday party at Pumpitup Avon. Since the girls are only 3, I didn't want to do open jump, to keep the experience safe for them. It was great and they loved it. There were 3 monitors which seems like a lot for a small party, but there is risk with everybody jumping around and rules need to be enforced. The monitors took pictures during the jump time and there was a slide show while we ate which is a nice touch (internet access to the pictures they take costs extra) The adults in our party were able to play too and the girls had a blast. One hour was perfect for the jump time. The party times are set to one hour jump and 1/2 hour in the party room. It was really rushed to eat pizza and cake and ice cream in a half hour. There is a required short safety video before jump time and the clock in the waiting room was several minutes slow. The clock in the jump room was fast by several minutes. With cell phone times being exact, it's easy to know the real time and their clocks should be accurate. Also, we got there early to be sure we had enough time for check in, and just stood around. They could have showed us the video while we waited, instead of taking precious minutes out of our jump time. Private parties are expensive so every minute counts and the kids didn't want to leave even after an hour! With a little tweaking and some flexibility on the part of the staff, this would be 5 stars.
