I don't think I would ever sign up for the monthly membership, but as a one-off place to hold a…read morebirthday or other kid-friendly event, Sky Zone is a decent place to let your littles burn off some energy, but comes with some MAJOR caveats that one should be aware of, before paying the (rather absurd) price of admission.
Two of our sons have birthdays close to each other, so we hosted a double-birthday celebration here, bringing our entire brood of (five!) boys with us, plus a few of their friends, and let them run rampant for two hours! There's a small, fenced off section for little-littles, which includes a foam block pit and three trampolines. Beyond that, there are a couple of other, much larger trampoline/foam block pits for leaping into, trampoline basketball courts, balance-based obstacles, a full sport court, a massive trampoline-only section, and right of the front desk, a small area with a jungle-gym and a few projector-based games. In short, there's a lot to do, for just about everyone, of any age or size...although my three year old seemed to enjoy just running around the entire building and making towers out of foam blocks, more than anything!
The price is a bit of a sticking point, though. First off, unless you sign up for the membership (by the way: don't!), you're looking at something like $27/person, regardless of age. And when I say regardless of age, I mean REGARDLESS of age. Yes, an adult costs the exact same price as a 1-year old toddler.
For comparison, indoor playgrounds like Kids Empire charge $20 per child, with one adult included free with each child...and there is no two-hour time limit; that's an all-day pass; you can even leave, and return later the same day, if you like! This means that my wife and I can take our two toddlers, and let them play from morning til night, for $40 bucks. At Sky Zone, it would be over $100 for the same four people, and only for two hours. Want to extend your time? Pony up for the membership, or drop another Benjamin. That's bananas.
Another annoyance, although seemingly loosely enforced, is that apparently you must wear Sky Zone branded grip socks, purchasable from the front desk at something like $7/pair. Now, when we bought our passes, we were not informed of this, and none of us had them; we entered the park and played for more than an hour, before one of the wandering attendants told one of our five kids that he needed to get out and get "proper" socks.
This didn't happen to any other child or adult, so I couldn't even begin to tell you how this policy, and its enforcement, actually works, but be warned that there may be a "tax" of up to $7 per person, if the lackadaisical staff feel like cracking down on it. We ended up buying a couple of pairs for our toddlers, because they kept losing their own socks, due to friction, in the foam block pits, and the neon green baby socks were both longer, harder to remove, and easier to spot and retrieve from the pit, when they came off.
Everyone, myself and my wife included, had a great time here, but it's a shame that the whole experience at Sky Zone was tarnished by predatory pricing, inconsistent enforcement of policy, and the aloofness and indifference of the clearly clueless staff (save for the people running the snack bar, strangely enough). So while your kids are likely to have a blast at Sky Zone, even parents who sit on the sidelines will feel like they've had to run the gauntlet just to provide a few hours of entertainment for their children. I felt more drained by the pricing, the operational headaches, and employee incompetence, than if I had spent those same two hours doing backflips into the foam pit. Having fun shouldn't be this hard, or expensive.
