Evil cast member thrill:
At Magic Kingdom and Epcot, while we may let you into the turnstiles before park open, you aren't going to get very far. So, I love to see sweating and pushing and dodging and weaving down Main Street, especially on a hot summer mornings, only to find that there is a rope blocking you from further entry into the park at all the bridges. And then all these people who calmly walked down Main St are standing next to you 5 minutes later at park open when they drop the rope and let you into the rest of the park.
But my pure joy comes from the opening of Epcot. After entering the turnstiles, people sprint, rapidly sprint, for their favorite ride, only to find a huge rope in the tip board/front of the fountain area. So as a cast member on the other side of the rope, I take great joy in seeing people get all sweaty and bothered only to find their efforts thwarted. Then we have a lovely opening ceremony, so people seem content with that. But then the people that have lined up by innoventions west, in order to get closer to Soarin at rope drop, or Innoventions East, in order to get closer to Test Track, find themselves thwarted because the cast members actually drop that rope last. And then we have a WALL of cast members preventing you from going anywhere fast, who don't take kindly to running and sprinting to the nearest ride. And we will send you back! Mwhahahahahaha.
