Every Halloween weekend, it's a citywide scramble to find the best party at the most affordable price -- and it's not uncommon to end up fighting for space in a cramped venue wondering why you didn't plan better. This year, climb aboard A Nightmare on the Hudson for a three-hour party cruise featuring a terrific DJ and a well-stocked cash bar. Wear your best Halloween costume and sail scarily away for drinking, dancing and celebrating this ghoulish holiday like never before.
