I would choose the Plaza but you have to be ready to lay out a pretty penny in order to stay there. There is another hotel called Hotel Pennsylvania. It was built in 1919. It is beautiful, more affordable, and located right across the street from Penn Station. I would highly recommend staying there. Unfortunately, the hotel is slated for demolition. Even if you don't stay in the hotel, please help try and save it. Please go to
