I'm hoping someone will have some suggestions of things to do near JFK. We are flying into JFK from Germany and will spend 4 days in Manhattan. We are then going to fly out of LGA to Denver for 3 weeks and fly back one day before our flight back to Germany out of JFK. Our flight from Denver will get in at 6:00 p.m. Our flight back isn't until 5:00 p.m. the next day. I'm debating if we should stay in Manhattan for the one night and do some more sightseeing the morning before our flight or just stay closer to the airport. WWYD?
