New York City is one of the best cities to vacation if you are on a budget. There are so many ways to see the city for free or very little cash. On my most recent trip we did the following...
Free:
-See the Statue of Liberty via the Staten Island Ferry
-Attend a street festival (September has a lot)
-See the 9/11 Memorial
-Walk around one of the cities many parks (Central Park, Battery Park, etc)
-See the beautiful architecture in Grand Central Station or tour the NY Library
-Highline Park
-Walk the Brooklyn Bridge
-Walk around the city, especially Time Square
-Plus so much more!
