Thank you for flying British Airways.

Heathrow to JFK 7 1/2 hours flight

Theres lots to do but it also depends on the a mount of time you plan on staying. 1 or 2 weeks? I can give you some tips.
If you like sight seeing theres plenty to see, museums, ground zero, statue of liberty, the Circle Line boat around Manhattan...etc, rent a car and take a drive out to Long Island and hit the outlet stores and get some great clothes for cheap and take a nice drive on the South shore of the L.I. and see the beaches and the roads 1Arm and I rip apart

Theres plenty to do and the rent-a-cars are cheap. As for getting a hotel you should stay in Queens/Long Island City, you can save a lot of money and its like a $2.50 train ride in to Manhattan and if you have a rent-a-car you can rent it the whole time youre here and leave it parked at the hotel. Need any help with ideas..etc, just let me know.
