This is my least favorite line in all of the parks, i think. I actually started to have an anxiety attack last time. They were having some sort of issue where the buggies kept stopping and starting every few minutes, so the line was very backed up. We were crushed together in the outside, just before the doors into the building area for a while. Then in the room before the stretching room. Couldn't move in the stretching room at all, and as much as I usually enjoy the effects in there I had to turn and bury my head in DB's chest to focus on breathing because I was getting so panicky. Once the door of the stretching room opened....we still couldn't move. The line in the loading area was back up to the door. It kept breaking down, and once we made it into the loading area they still just kept herding more people into it. I almost had to leave before we finally got on.
I'm hesitant to get on again because of this experience, and that was with FP.
