Well, we hust happened to be at Dland last time. They were setting up red carpets and stages so we asked a CM what was up. When we found out what was happening my sister and wife went home to get cameras and I held a spot on the edge of the red carpet.
So, last year all you had to do was buy a ticket into the park or have an AP.
Not sure how it will work this year though. It's great fun!
