Be careful when getting a taxi after you get off the cruise (we wer on a Norwegian cruise but they are probably all the same). There are guys waiting on the sidewalk outside asking you where you are going and offering a fixed price even if not going to the airport. Just CROSS THE STREET and pick up a regular yellow taxi. We were going to a hotel in Manhattan, which I new was close by. The taxi cost us $8.10, and the guys trying to give us a price quoted us $30 and $35 dollars. Yellow taxi's have a fixed rate of $45 from Manhattan to JFK as well. Taxi's are obligated to take you anywhere in Manhattan or JFK if they pick you up.
