Website says 20 or more qualifies for group rate
I am not sure just call them
They do for larger groups but we had a tour guide set all our stuff up. We had like 90 though. They moved us through pretty quick. Once you get to the top it'll seem like a never ending line but it goes fast as they monitor your time and move you on. There is a gift shop at the top. Save your money for the one you don't see until you take the elevator down sooooo much more stuff!!!
Not sure on the group rate thing. But I would hope they would...
Yes you can, but you have to contact the administration.
I believe there is but you would need to contact the facility. Also, due to the size of your group, you may need to schedule an alternative time - either very early or late - and there likely would be an extra cost, if permitted.
