Spending Time in NYC?
If you're going to spend time in NYC before the wedding, we recommend taking a cab from JFK, or for a cheaper alternative, the AirTrain. The AirTrain runs counter-clockwise around the airport terminals, so hop on the one that takes you to Jamaica Station.
Jamaica Station is a hub for subways servicing Brooklyn & Manhattan, as well as Long Island Railroad trains servicing Queens, Long Island City, Brooklyn, Long Island, and Manhattan. From Jamaica Station, trains run regularly to Penn Station, which is 34th Street & 7th Ave in Manhattan.
