I lived there for several years. There is so much to see. Museums and the garment district (go fabric shopping) ....maybe u are not going there for that but its a fun place. Take the ferry over to Jersey. Sax and stores downtown. The guggeheilm museum. Small museums and food. Great restaurants. I don't know what is new now. I love china town. It is small but interesting. U can take the subway to most of these places. Try to see a play. The matinees and cheaper but just as much fun. Go do the morning shows and Katy trly to get tickets in advance. Most of all have fun and be careful and safe.
