Wall to wall trampolines. I went with my family using a Groupon deal. The main trampolines get pretty crazy, especially on a Saturday, which is when we went. But for little ones, they have a couple bounce houses and a trampoline area just for them, which is nice. Even so, while we were there we saw a little one get a bloody nose, so it does get a little dangerous. My kids (ages 7-2) had fun for almost an hour, then they got tired. If you get a "fun pass" all the extras are included, which means the foam pit, dodge ball, and the bull ride. They were fun to try but not worth the extra money in my opinion.
