We booked the Landmark cruise which lasted about 90 minutes. There were a few things that made this a perfect thing to do. First, this was the first time our kids visited NYC and this cruise gave us a beautiful view of the cityscape. It departed on the Hudson at 42nd St., looped around to mid-way up the East River and back. Second, a tour guide offered various historical comments about different landmarks which was great for us since we’re not familiar with New York. Finally, they drove us past the Statue of Liberty and seeing it up close was great.
I would highly recommend it.
