It's sort of similar to how in the Hotel section, they didn't focus on the Devil's Night theme, so there weren't scareactors dressed as the ghosts of famous American serial killers like in the episode. At first I thought it could be because they are actual serial killers and that could stir up controversy, but seeing as how in the Orlando maze, during the Murder House section, they recreate the nurse kill scene by the home invader, who in the show was the serial killer Richard Speck.
