It is easy to get to NYC from Cape Liberty but your problem is that you will have your luggage with you. There are no left luggage facilities in NYC since 9/11 due to fears about security. If you are going from EWR you could see what the earliest time is that they will check your luggage in which will give you a few hours free to nip into NYC on the train. If you are going from JFK then I would forget it and resign myself with a good book for the wait. Unfortunately RCI do not run excursions that drop you off at the airports which would be a good way to kill time.
The Empire State Building is certainly worth a visit but don’t go to the Imax Theatre showing the views of NY as this I have heard is a real waste of money. The Rockefeller Center with its skating and great views is another good one. Bearing in mind your visit is in February The trip to the Statue of Liberty and Ellis Island would be fairly cold but the Staten Island Ferry is a good way to see them in the warm. The Guggenheim Museum and the Metropolitan museum are extremely interesting but one of the best places to go, near the middle of Central Park is The American Natural History Museum. You can check all this out on the net with costs and opening times quite easily . Greenwich Village and Little Italy are superb for eating in and Grand Central Station is also interesting and warm…Hope that Helps…..Leanne Dow.
The luggage problem can be solved by booking a hotel room on a daytime basis and it is relatively cheap in February. You then have somewhere to leave luggage safely and to have a wash and brush up or even a rest but book it preferably before you go....Leanne Dow.
New York Manhattan is a good 1 hour away - you may not get off the boat till 10.30. We checked bags in at the airport around 11.30 and went to a nearby shopping mall in Newark - free bus from the airport but 4$ back. Over 100 shops Abercrombie & fitch Bloomingdales etc and loads of restaurants.
May be an option if you have already visited NY
