This is a great place to take your toddler to burn some serious energy. My 2 year old loves it here. The membership amount is tax deductible which made the $160+ easier to swallow for our family of three and they frequently have deals or promotions that get in guests for free on a regular basis.
I can see how this place would get boring after a while if you have a kid older than 5-6. But for the older kids, the first level is the best spot for them. The younger the kid, the higher in the building you should go. My kid spends most of his time on the third floor and there is even a great shoeless room geared specifically for kids under 3.
We love it here.
