We went to Get Air Sportsplex, which boasts that it is the largest trampoline park in Utah, and the kid's all had a blast. Admission is charged by the hour, and we chose to stay the full two hours that the school had reserved the park. I had lots of fun playing with the kids, and we all left a bit flushed and tired.
The big kids spent quite a bit of time doing large jumps and flips into the foam pits, Princess took small jumps, and Squirt just ran right in. It was extremely difficult to get out there, and Squirt especially enjoyed lounging out amidst the foam cubes.
There was also a large area to jump and run to your heart's content. Gizmo and Spike mastered jumping up onto the raised platforms and landing on their feet quite well. The trampoline ramps and slides were also a lot of fun.
