Aser, I just got back from a week in NYC, it was a blast. Don't be afraid of the NYC subways, they are safe, cheap and very efficient. We stayed out at Columbia University on 121st, and rode the subways all over town. we did most of the tourist things. The Empire State building is higly over-rated, and takes a long long time in line ups to reach the top. The Staten Island Ferry is free, and well worth the trip over, great views of the lower Manhattan skyline. The area around Pier 17 at the foot of Wall St is nice, sit and drink Margeuritas and watch the tour helis come and go. You can also watch a line of corporate 76's and AB 139's in the AM and PM.
We went to several Broadway shows, but i'm not sure that they are still running now? There a lot of great museums to see, we spent one full day at the Museum of Natural History...Wow.
Have a great time ! !
