I was here about 35 years ago. It has changed so much. It is an amazing and awesome experience. We got there early and had not problem getting thru security. The museum is amazing and the displays are awesome. We didn't have to wait long at all for the tram ride up. The entire place is air conditioned. Spend about 30 minutes at the top. The gift shop and cafeteria are great.
