Queen Mary Dark Harbor: Long Beach, Calif.
The RMS Queen Mary
– a retired ocean liner that now serves as a hotel and museum – is
transformed into a nautical nightmare each October. To enter the
attraction, visitors must maneuver
through a fog-filled tunnel of cargo containers, which leads to a series
of spooky ship-themed mazes. When you've had your fill of frights, Dark
Harbor also features a dance floor with live music – though there may
be a ghoul or two lurking here as well.
