Comfy shoes is a must. It is a great city to visit .... great variety to appease almost anybody's likes. The theater district is the draw for me ... with Broadway shows, Off Broadway and off off Broadway. And I loved the museums, historical sites, bookstores etc. It is a good idea to arrive on a Thursday (at least in the Theater District) when it is at its cleanest because by Monday afternoon there are trash bags sitting out on the curbs waiting to be picked up. I received the best service at the Edison Hotel in the theater district but I'm sure there are others just as well. It helped that I was with a group that was very familiar with the theater district and got to go backstage on a couple of shows. Have fun!
