You can get same day walk up tickets on a first come first serve basis Monday - Friday. I arrived at 1:15pm and they were going pretty quickly. I stayed approximately 4 hours and didn't even get half way through. It will take you multiple visits. I can't wait to go back!
I agree with Vania Dyson. We started in the lower level...you need 2-3 days to see everything.
I really don't know, sorry
Thank you everyone, can't wait to visit.
