Hi Beth, sounds like a good time to be visiting NYC. You asked me about my stay there with P&L. Well. We were there less than 24 hours... so I can give you a quick rundown of a quick trip, but I'm sure nearly everybody else has more interesting & important things to recommend.
We stayed at the Empire Hotel ($100/night = internet rate). It was OK and fairly well-situated across from the SW corner of Central Park & just east & across the street from Lincoln Center. Not a dump... nothing fancy.
We ate dinner with abuzz friends at Il Violino on 68th & Columbus which was within walking distance and seemed (to my uncultured tastes) to be a very good Italian place.
Merry Andrew met us and helped us find our way around, and of course we met Bert for lunch, which was great. My favorite thing to do was taking the ferry to Staten Island & I was happy to see Pooh & Co. at the Public Library. We also saw bits of Rockefeller Center & peeked in at St. Patrick's Cathedral. Hmmm. That was about it. The things we WANTED to do but didn't have enough time were to visit every museum, especially the Cloisters and to do loads more shopping. I would have loved to spend time in Central Park people-watching, and also in Greenwich Village looking for the perfect Italian grocery, but that could be because I'm currently reading
Lucia, Lucia. (not highly recommended, but fun)
I can say from previous trips to NYC that a day or two spent at the Metropolitan Museum would not be wasted.
