Thanks Kodi and Gotravel for the tips and help:)
I am really looking forward to travel alone ( though a bit scared...) as I can do and visit whatever I want to!!!
I will make sure not to miss the Century 21. It must be great digging there, I love that!

You can take a helicopter from the AA terminal to downtown Manhattan, starting March 13.

8 minutes. Introductory fare of $139 each way, permanently $159.

From April, you can also go to midtown.
