It is possible to visit Ellis Island on turnover over day. Or if you have time before the ship sails. Take south Brooklyn route from Red Hook to Wall Street. Purchase tickets at the ferry, just to the left of the ship. Walk to Castle Clinton in Battery Park. Purchase tickets at the park. Ferry to and tour Statue of Liberty and Eilis Island. Take ferry from Wall Street to Red Hook. Walk back to the ship. We were able to see everything we wanted to see without spending an extra in New York. We did visit the Muesum first and was not crowded at all, then went to see the Statue. If you want to visit the top, you must purchase in advance. Fun day, we were happy that we could do this on our own.
