There is a huge area with tons of different sized basketball hoops (on padded flooring)
Then there are a ton of different playscapes--different sizes, different styles, etc.
They change the floor around every couple of months. They also change some things on different sets--like the type of swing it has on it, or it may have rings one time and a bouncy thing the next. There are usually between 10 and 12 sets displayed at a time.
They also have two huge trampolines!
There are also scooters, cars, bikes, bouncy balls... all sorts of toys.
It use to be free to go in and play. It go SO popular though, that they had to make some rules. Now there is free play from 9 to 11 on Tuesdays, Wednesdays and Thursdays. If you want to come at a time that does not fit into those hours, it is $4 per child and they can play as long as they want. If you really want to go there a lot, you can get a year membership for $99 and go whenever. It's great for those really hot days in summer when you can't be outside, or those rainy days in the fall and spring. It's not heated (or at least not well), so sometimes in the winter it gets cold in there. The kids are fine, because they are running around. I, however, have to keep my coat on. Not my idea of fun! :)
If you are not local, you may want to check some display rooms in your area to see if they do the same thing. If they don't, you may want to give them the idea! ;) Little Man LOVES going to Recreation Outlet.
