We will be spending a few days in Manhattan before traveling to Islip for a conference. I'm not sure where we'll be staying on Long Island, but right now I am looking at Hauppage (Hampton Inn). We'll be flying into JFK and out of Islip. Is it better to rent a car at JFK the day we depart for Long Island, or try to take public transportation to our hotel and then rent a car from our hotel, or at the station? I assume we will need a car in Long Island to get around. If we take the Long Island Railroad, can we get a taxi at the station to the Hampton Inn? And what station would work best for that? Thanks for any input.
