Just had our son's 7th birthday party there yesterday, and, to put it mildly, we were impressed... and all the kids loved it there (as the name would suggest). It totally surpassed our expectations.
To be honest, we didn't know WHAT to expect, especially since there were so many different activities planned, some of which may not have appealed to all the kids. These misgivings were entirely misplaced: from the moment the kids arrived, they were engaged in the terrific play area, with the inflatable jumper, to the rolling foam rides (expertly staffed by three very "into it" Party Helpers), and much else besides. After nearly an hour, they transitioned to the lego-building (this was the party theme), mask-making, and play-tattooing activities; we weren't sure the kids would take to it, but they were completely enthralled, and didn't want to move, even for lunch! They finally transitioned into the dance room, and went crazy dancing to a CD we brought with us, with songs we'd put together for the occasion.
The owners have a nontrivial list of regulations, meant to ensure that the kids are kept out of harm's way, and we'd thought they might be somewhat sticky about altering things. It was the opposite: we always felt that it was OUR party, and they were there to make it a success. They helped put up extra decorations, switched around the order of some activities, served whatever we brought, and had more than enough of everything on hand to accommodate all the kids (about 30) and as many adults as were attending them. Everyone was cheerful and professional, and the place was spotless (commented on by several of the parents, in fact).
Yes, the party was pricey, nearly $1000 with everything added in (helpers, party favors, food, etc.), but it was TOTALLY worth it. We'd had his prior parties at museums and such and, while the kids enjoyed themselves there, they did not *interact* with one another. Here, we felt the kids were getting to spend time with one another, and with our son. Not having to shop for plates, forks, napkins, hats, party favors (I could go on), or having to CLEAN UP... it was all a huge time-saver and stress-reducer.
But the most important part was this: the kids obviously had a blast. We kept taking video to see them frolicking about. Again, we were uncertain about how it would go over, but, after it ended, we said to one another, "well, that really went amazingly well, didn't it?"
We'd have his party here again in a heartbeat.
