Also, guests are moved automatically through the rooms so the queue to get into the room goes fairly quickly. You are allowed to ride multiple times to get the prize again, unlike Q quests where you can only get the prize once. If it is like the Everest ride-a-thon, there will be a different prize for each day; something on Saturday and something else on Sunday.
One good thing the Staff did the last time was to ensure that if a guest got "bumped" out of the ride and ended up at the "front door" of the next room, they could get back on instead of having to start over. Previous events, this problem was overlooked (Halloween Maze) and guests that were bumped had no way to get back into the maze.
