We've probably been here over 100 times. The great thing about this place is that they keep updating it. The newest thing is the outside playground.
Inside there are three floors with various activities. The climbing structure on the bottom floor is the flagship apparatus in the entire museum. Even adults can try their hand at going from the bottom to the top.
The art room always has something different every time you go. Kids of all ages will find different activities that will challenge them and keep them occupied for hours.
A little side perk is that an annual membership can be partially tax-deductible.
This is definitely a great place to visit with kids.
