Dark Harbor

The only thing better than a haunted attraction is a haunted attraction on a giant boat. You’ll find all the usual horrors here—fog, mazes and countless monsters. What sets Dark Harbor (back for the first time since 2019) apart is its use of its surroundings; the dark, cramped confines of the Queen Mary are already pretty spooky even without monsters—just be prepared to climb a lot of skinny staircases. The event’s 2024 return includes experiences set in the ship’s swimming pool, kitchen, engine room and staterooms.
