Bounce U has 2 rooms that each have inflatables to jump in/play. During open bounce they will let you in each room for a half hour at a time, so that gives you 2 times in each room. Each room has a big slide. One room has an obstacle course, a basketball/slide/jump, and a football throw. The other room has a nerf gun type thing, a small bounce house/slide, and a wrecking ball-ish bounce area. That one is not quite ideal for young kids but older kids love it.
The place is not the cleanest. I really noticed that the crevices of the slides were pretty dirty. Last time we were there, the bathroom was teeming with ants!
But my son loves this place! We have gone for Open Bounce and Preschool Open Bounce. He is 3, so the preschool open bounce is the best for us because all kids are 5 and under. The regular open bounce is great for older kids. I think he got a little overwhelmed with the older kids doing crazy jumps. You have to check their calendar for the open bounce times, because it isn't open to the public all day like I had originally thought. I wish they had more preschool open bounce times. It's usually only 10-12 a few times a week. After preschool bounce they hand you a juice box and snack on the way out which is a nice touch.
