Took three kids, 3 (boy), 5 (girl), and 10 (boy) years old this morning for the kids jump at 9am and they had a blast!
The place was clean, had plenty of friendly staff and the facilities were new and plentiful. No lines, no waiting just open play the entire time. The registration process was also quick which we did there (although I would suggest the doing this online before hand).
We chose this place because they had a special jump time from 9am-10am for kids 6 yrs old and under which turned out to be perfect for the little ones. They were able to jump and climb on everything with ease and confidence. They love Ninja Warrior so the fact that there was a Ninja Warrior like course that even they could try was absolutely thrilling.
Once the big kids were allowed to come in the place did get more populated but not so much that it became unsafe for the little ones who stayed to play. They also had a small section for just the little kids that stays open which was nice. They also do not allow too many kids to enter the place at once so I would suggest calling ahead or getting there early as I saw some people having to wait to enter. Additionally, there were plenty of areas to rest and sit for parents/guardians.
We didn't feel the need to rent any lockers as they had plenty of cubbies and we only had shoes and other non valuables to store. The only thing I would improve on is that they do not allow outside food in the place. They have a few vending machines with drinks and chips but I see no reason why they shouldn't allow people to bring in at least their own water bottles and snacks to be eaten outside of the arena.
Overall it was a great experience for all ages!
