Gaffes

Around 25+ minutes, Natalie is with Quinn roaming in the hell fest and she has two pretzels in her hand. It is shown that she takes a bite, but in the very next second the pretzel is still intact. The next second, a mouthful piece of pretzel is gone.

When The Other goes into The Hell labyrinth, he picks a real ax. Lately the girls verify that every device into the labyrinth is fake. It is irresponsible to include a real ax in any fair stall. No insurance company would cover such a negligence.

There are no fire exits in the mazes. These have been mandated across the country following a 1984 fire at the Haunted Castle walk-through ride at Six Flags Great Adventure in New Jersey.

At the end of the movie, a television reporter says four people have died in the incident at Hell Fest. While at least one other person is seen being murdered, they may not have been found yet and the reporter is just stating the current info.

The gang gets VIP bracelets when they enter Hell Fest, meaning they don't have to wait in line. Later, after Gavin gets separated from the rest, the others convince Natalie he'll catch up to them in line for the next ride, even though they're supposed to be able to go around queues with their VIP band. Then, when actually reaching the next ride, they're still surprised there's a line for the VIP access.
