You will get to see many things that are NOT visible from land. Breathtaking scenes of Brooklyn, the Statue of Liberty, Governors and Ellis Islands and Manhattan. If you get a daypass you can cruise up and down the Hudson River all you want. It's worth every penny.
After visiting Brooklyn Bridge area, we took the one-way $4 water taxi back to Long Island City, Hunters Point.
It was a great ride, beautiful vistas. Will do it again. You purchase the ticket from a machine, then wait at pick up
point. There are various boats unloading, so if not sure ask.
We had a New York city pass and when we went to get a ticket, the girl said,"the machine that scans the passes isn't working" and she sits there waving this scanner in the air like it was alive or something she wasn't very helpful either just a moron really
