There's no better theme for a Halloween party of monstrous portions than the majesty and tragedy of the Titanic. Grab your best ghouls and climb aboard the Spirit of Boston -- if you dare -- for the Titanic Masquerade, the ultimate halloween dance party that summons the spirit of the doomed cruise liner complete with ghosts and ghouls that have risen from their watery graves. Costumes are required and masks are preferred on this 3-hour excursion aboard Boston's luxurious and massive two-decked yacht. Celebrate the spirit of the season with a monster mash of Boston's four hottest DJs spinning club hits throughout the many dance floors. Drinks will be available for purchase on board at a cash bar and if you spring for the VIP ticket, you'll get priority boarding and have access to a special dance floor and DJ.
