I have looked in the guide book, and on the airport websites, and googles, and I still don't understand how to do it or how much it costs. Is it very difficult/not worth it?
DH and I are arriving at JFK, and departing from Newark, and while in NY will be staying on the Upper East Side. Trying not to be too extravagant so want to avoid taxis where possible, but I am pregnant so don't want to much stress/carrying luggage.
Can anyone help with simple instructions and prices?
