I am attending the conference from Thursday through Saturday only. A friend recommended a nice mid-priced luxury hotel at 81st and Central Park West that has two-bed rooms for $175 + tax, with an upscale onsite restaurant, that is a short walk to the 81st Street subway station. All of their rooms have either a north city or a Central Park view. They also have 2-room suites for $270/night which include a living room, some with separate sleeper couches. http://www.excelsiorhotelny.com/
Or I could see sharing a 2-bed room at the Hampton Inn Times Square south for around the same price. The Hampton there has a $139/night AARP rate for a single king room which includes breakfast too. This hotel is on 39th Street between 8th and 9th Ave. http://hamptoninn.hilton.com/en/hp/hotels/index.jhtml?ctyhocn=NYCMAHX
Let me know soon if you might be interested.
