We called ahead because it was supposed to be buy one get one free tours. The lady told us just to come in and we did. Well turns out you have to reserve the tour, we missed it and just walked around our selves. This could have been avoided if the employee would have told us to reserve we were literally on our way. We explained when we got there and they straight up didn't care they looked miserable and were not helpful at all. I'm giving this 2 stars because what we did see was nice and security was helpful. I will not go again.
