You swipe the credit card you used to purchase them and enter the confirmation number and it spits out the tickets. You may want to purchase the lanyard as well when you get there (or bring if you have). Otherwise you have to keep taking the tickets out. The tickets were the same price, adult/child, and we did purchase 4 adults and 2 kids, but it spit out 6 adult tickets. I mentioned it at the entrance gate, but they said it didn't matter.
Have fun!
Thanks a lot! Guess I better bring that credit card with me!!
