I love New York City and want to add a few things not already mentioned. Central Park is wonderful! One trip we took the subway to the "top" and then walked all the way through. It took about four hours but it was such a great way to spend a quieter day after several days of touring. This past summer we took a guided bicycle ride through the park. It was great! Already mentioned was to walk across the Brooklyn bridge and to ride the Staten Island ferry. Both of these are free and fun! We go to NYC every year or so and always love it! May should be a perfect time of year. Enjoy!!!!
