If I hold it in Port Jervis, there is an NJ Transit train line that goes all the way up there so you don't even need a car. If it's in Stony Point, you can take a Metro North train to Ossining, NY (Westchester) and then take a high-speed ferry across the Hudson. That will put you in Haverstraw, NY which is right next to Stony Point so I (or anyone) can pick you up easily from there.

By car....
From the George Washington Bridge, Stony Point is about 45 minutes on the Palisades Parkway (GWB connects directly to the parkway). Port Jervis is about 2 hours by car.
