Well, I took my 1.5 year old son and 6 year old daughter for the Open Bounce. We drove from Litchfield Park because of the reviews. The problem is that they don't tell you what sort of equipment is available. The attendants were kind and were keeping an eye on the kids- which I appreciate since I am too short to see over the edge of the one bouncer my son could play on. I took him on the slide twice and them he was pretty much done. In all there was 1 tall slide, 1 challenge wall (the kids run up the incline as high as they can and slide back down), 1 "bounce" castle, and 3 "bounce" games where the kids throw balls at stuff but doesn't really involve bouncing. Oh, and an air hockey table that occupied a lot of the dad's for awhile.
The price was certainly fair at $18 for 2 kids for 2 hours, but my son was in serious danger by some of the other kids (ironically, the oldest kids were the most careful- but look out for the 6-8 yr olds!).
My daughter liked it but was bored after 45 minutes. All in all it was really too crowded, too limited in stuff the kids could play ON, and not safe for my son. Not worth the hour long drive.
