Eureka!!! I have found a most affordable way for A New Englander to get into the Port of New York from Boston/Providence/Hartford....Take the Megabus then the taxi!! We are heading down to NYC from Providence RI for a cruise aboard the Carnival Splendor for the incredibly low fee of $4 pp/rt...the taxi ride is short (only a few blocks) and also inexpensive (approx. $10 pp/rt +tip)...Why Bother with driving (+parking) or Rail or Air!!
It is an added reason for cruising out of NYC as the bus travel time coincides very conveniently with the other transportation choices at far less expense. Remember.....tickets need be purchased via internet several months in advance to get the lowest rates!
