Just held my 6 year old's birthday party at 3-2-1 Bounce. These places with inflatable play structures are all the rage. If you just have to take your kid(s) to one don't make it 3-2-1 Bounce.
The play space and structures are fine. But it's way overpriced for what you get. Their restrictions border on silly. Some examples - the only main dish food they allow for a party is pizza, which they have to order from Papa John's with a nice markup; they allow you to bring in carrots, but not fruit (so all our sliced apples went unopened); don't even ask about soda, because that goes into the "we have to order it" bucket. At least we could bring our own cake.
Their promotional material says you get a private party, but they don't tell you that this includes sharing the play space with another party. I understand that from a logistics standpoint, but their materials should make that clear because our kids were surprised when all these younger kids were running around with them.
And best of all they provide almost no supervision on the play structures despite claims to the contrary. I didn't see an employee come into the play area for the first 30 mins we were there, and while she was nice enough she spent as much time on her cell phone as she did watching kids. And she never enforced the rules, which got interesting when the party of younger kids experienced a 4 kid pileup on a big slide.
We ended up at this place because the one that my son knew about - Pump It Up - was booked. I've not been to that place so I can't compare. But this one didn't impress me and I cannot recommend it anyone who wants to play at one of these inflatable structure playgrounds.
