FROM THE AIRPORT: From JFK, it is worth getting a yellow cab; journey time is usually 30-45 minutes. Alternatively, try the New York Airport Service Express Bus into Penn Stn, Grand Central Stn and Port Authority; or use a shuttle minibus like Go Airlink or Super Shuttle which will drop you at your hotel for only a little more than the bus. From Newark, there is a fast train (30 mins) to Penn Station, operated by NJ Transit. Otherwise try the Olympia bus into Penn Stn, Grand Central Stn and Port Authority. From La Guardia, there are taxis, shuttles and buses.
