The Kangaroo Kingdom is essentially a toddler's gym. Everything is padded and they can run around exploring all the different equipment. I think that the open gym is fun, the classes held by a third party are good (for instance the baby sign language class), but the "kangaroo classes" (for instance Junior Bouncers) are a waste of money. My experience was that you pay $140/10 week session for the kids to essentially have an open gym. It's $8 to go to an open gym (unless you prepay then it's a little less), but I think $8/child/hour is pretty expensive. Toddler open gyms (6 - 36 month olds) are 45 minutes to an hour. Children's open gyms (6 months - 5 years) are 2 hours. Also, the gym area is quite small. Overall, I think it's fun to go to occasionally, but it's not worth a weekly, or even bi-weekly visit.
