My daughter will be flying into JFK from Paris early evening on a Wednesday. She'll be staying with relatives in Scotch Plains NJ and would prefer to avoid having them pick her up at the airport. She will be hauling heavy luggage with her (she's been living overseas) but is adept at public transit. Any ideas on an affordable, not-too-complicated way for her to get from JFK to a reasonable pick-up point in NJ? Thanks.
