This was my 2nd time here and I only returned because our children wanted to come. Last time my Husband and I were here was in 2008. Everything seemed the same, nothing really changed. It was interesting to talk to the kids about our bodies and watch how excited they were to learn more. Reason for only 4 Stars is you can't take pictures inside and must turn off phone. Sort of lame you pay all that money and then you can't even take a picture of your kids enjoying it. They offer to take picture but of course you have to pay for it. Great to go to once but not twice!!
