Tickets are on the pricey side but the attractions are great. Lots to see! Exhibits are clean and fun. Definitely recommend going early on a week day. We were there at 9 am when they opened and left at 2 pm. We still didn't see all they had to offer, but in July it was getting a little bit hot. We would like to go back some day.
