We were the first ones there, about 15 minutes after the place opened. It wasn't crowded at all, but then, it was a school day. At first I was worried that there wouldn't be enough to do, but my kid had fun running and climbing, getting pretty tired after an hour. It made for an extra long nap that day, which is my criteria for success. Once you pay, your good for the whole day, so we left and came back late in the afternoon to burn off more energy. They also have free wifi, so I was able to surf the internet on my phone, which was a nice bonus.
It is reasonably priced and good for an hour or two of activity. I think it would be best for a small group of kids, like a play date. It also sounds like an excellent party idea. We almost went back the next day too, but the weather cleared so we were back at the beach.
The major downside is that they don't allow outside food and drinks, that kind of bugs me, since it is clearly not for a good reason except to enhance their revenue (You can't bring a bottle of water in, but you can buy one there).
I couldn't help but think of was it could be improved, and came up with a few suggestions, More comfortable chairs for the adults would be one, as would beanbag chairs. Another train table would be good, and if they also had the plastic trikes, they could charge for the under 2 crowd (currently free, but not much for them to do, the inflatable stuff is too big). A ball pit would be good too, but that would take up a lot of space. The air blowers where not obnoxiously loud, but you could always hear them, they never fully faded into the background, so muffling or moving them outside would be good. Don't take the suggestions to mean I didn't like the place, I would go back there again even with no changes.
