Everybody in line is already in character, and that changes the whole park. On any other haunt night you are a guest walking through somebody else's production; on the thirty-first you are inside a crowd that dressed for this, which means the scares come from both directions and the queue is as much of the event as the maze. It is the hardest night of the season to get into for exactly that reason — maximum crowds, maximum energy, and a park that knows precisely what it has. Buena Park itself spills over: the costumes do not stop at the gates. The regulars will tell you the same thing every year. Hit your target mazes early, build in buffer time, and stop treating the lines as an obstacle, because that is where half of it happens. This is the night the whole thing was built for. Bring the friend who screams and the one who pretends not to.
