I'm not sure if you're staying the same hotel in Lower Manhaten that JY used last year, but it was a short walk from the 7/11 memorial, or battery park for a ferry to the statue of liberty. We used yellow cabs and the subway to get around. Also the hop on hop off buses. They are a great way to see the sights. The last morning we walked to Broklyn Bridge as far as the first tower. Whatever you decide to do, have a great time in the Big Apple.
