You have to fill our a waiver on the touchscreens or on your phone there before you even buy tickets. It was around $14 for an hour, plus $2 for their Skysocks if you haven't been there before. We went on a Wednesday night, and there weren't too many people there. The large trampolining grid was relatively empty and a lot of fun - jumping off the "walls" were great.
Dodgeball was slightly disappointing as the employees didn't take into account groups of people lining up. It was a first come first play sort of system, where even if the same group of people had been playing for half and hour on the court, they could still play, even if there were more people waiting. When we spoke to the employee about this, she just told us that there were no rules and told us to find another employee to open up a court for us, but none of the employees were free.
Overall, an enjoyable experience. Not sure if I would want to come during the weekends with more people and longer wait times. You'll also probably end up with a sore back, legs, and shoulders the day after!
