UNBELIEVABLE!! Times Square itself is worth a trip to New York. It really is the "Crossroads of the World." It is like going to a 24-hour carnival. We arrived in town at about 1am, by 2am we were walking around Times Square, and while most of the stores were closed, there were people everywhere. Also, we felt extremely safe, as the NYPD were on every corner, and I really mean every corner. There were sometimes two to three officers on the corners or walking the block.
Daytime is something else! The people, the traffic... it is like electricity in the air. Our main means of transportation was walking. I would suggest good, comfortable walking shoes. There really is something for everyone.
