Cruise passengers got soaked after the fog machine used during the spooky Halloween evening entertainment triggered sprinklers across the entire ship.

Holidaymakers were watching a show involving lights, dancers and music on the Royal Caribbean’s Symphony of the Seas when disaster struck.

Elise Eastep, 61, a rural mail carrier for USPS, watched as water poured from the sprinklers in every indoor area of the ship she could see.

They sheltered in a dry spot and watched as water poured for up to 20 minutes.
