New this season is the Grey Ghost Galley, a 90-minute, all-you-can-eat Halloween buffet in the ship’s Show Room on Dark Harbor event days. The Queen Mary lists seatings at 4 and 6 p.m., with diners receiving early access aboard the ship before Dark Harbor opens.

The ship is also launching Spookeasy, an event for guests 21 and older combining a cocktail and stories about the Queen Mary’s paranormal history with a short tour. The evening concludes at the ship’s N.o3 speakeasy with activities including crystal and palm readings and a meditative sound bath. Spookeasy is scheduled for Sept. 28 and Oct. 5, 12 and 19.

“Murder on the High Seas,” meanwhile, combines a multi-course dinner with an interactive musical murder mystery set during the Queen Mary’s final voyage in 1967. A matinee is scheduled Sept. 13, with evening performances Oct. 5, 12 and 19.

For those who prefer their scares on a screen, Movies on the Mary will show Alfred Hitchcock’s “Psycho” on Sept. 28, “Beetlejuice” on Oct. 12 and “The Shining” on Oct. 19 in the ship’s onboard theater. The Queen Mary also continues to offer paranormal attractions including its Paranormal Ship Walk, Graveyard Tour and Haunted Encounters tour.

The ship is celebrating the 90th anniversary of its maiden voyage this year. The Queen Mary departed Southampton, England, on its maiden voyage May 27, 1936, and arrived in Long Beach on Dec. 9, 1967.
