Not really geared for kids younger than five or six since there were so many older kids (10-12 years old) running around and knocking the little kids over. The employees were unhelpful at keeping it a safe environment. Very disappointed. I won't risk my kids safety.
On another note, it's way overpriced. It's ridiculous that you pay for admission and then you have to pay for lockers since you can't bring anything through the museum.
I had heard great things but we left after an hour of trying to do the different exhibits with our kids.
