New York

Run by Wall St. vets who live like every night's a bachelor party (or at least did), this just-launched service organizes every aspect of your gleeful penis gaggle, from nightspot discounts/reservations (Marquee, Sapphire, Penthouse Exec, etc), to transpo (tri-state spanning limos & private cars), to top flight entertainment. The latter's available either in-hotel, or at one of several blinged-out and semi-secret private lofts -- b/c even strippers shouldn't witness the horror of 12 dudes packed onto a twin bed.
