We just went to a birthday party here and the kids had a lot of fun. They say that 24 mos. and under are "free" in that they don't count for the headcount that you pay for and I could see why. It is definitely a place for 3 and up, in fact my three 1/2 year old had some trouble doing all the climbing required. The staff is consciencious and very helpful. I would definitely recommend this for a party.
