We came here all the way from the far west valley so I guess I expected more. The website advertises 3500 sq ft but the play area itself I don't think is that big. Just FYI. Basically, they have these cute little themed rooms (fire station, school, kitchen, etc) and there's stuff to play in the room. If you live in the area, I think it's a great place to let your kids exert some energy. However, I wouldn't go across town to come here ... at least not in the future.
I think your younglings will have fun. Toys are a bit old but usable. Plenty of carts, strollers, and ride ons to spread around.
