The Shark Reef attraction at Mandalay Bay is getting dressed up for Halloween. On Saturday 29th October children 12 and under in costume can trick or treat at Shark Reef for free. The normal sounds of the attraction will be replaced by spooky sounds and music. The walls will have ghostly decorations as well as pumpkins and the staff will hand out candy. It sounds like a fun time for the kids and a little different than the normal trick or treating.
