Hello!
NY has something to offer everyone. If you like sports, you can see the Yankees, or the Mets are cheaper, and the Cyclones are even cheaper and are located right next to the Coney Island Amusement Park and the beach :). I recommend seeing places outside of Manhattan, like Williamsburgh in Brooklyn, and Astoria in Queens. In Manhattan I recommend the Village, South Street Seaport, and Central Park. Let me know if you need any more information and happy travels :)
