This place looks terrible from the outside. Don't be discouraged. As a plus, they have free parking as soon as you pull up. Woohoo.
So, I'm not quite sure how to describe the inside. All the kids seem to be having tons of fun. There's lots of stations and areas for them to move around to. The climbing station is pretty awesome and the kids all appear excited to complete it. You may want to bring a raincoat/change of clothes if you are gong to let your little ones play in the water table.
At $7 a person, it is very reasonably priced for a couple of hours of fun.
