For big convention needs in the Big Apple, Hilton New York has you covered. Situated in the midst of the city's business and media centers at West 53rd Street and Avenue of the Americas, this is the largest hotel in Manhattan. A multi-million dollar renovation included two new floors devoted entirely to conference space. More than 150,000 square feet encompasses classrooms, theaters, banquet rooms, receptions areas and a selection of suites. Better yet, planners will make sure that every detail is taken care of, right down to pens for attendees and ice water on the lectern.
