I just purchased a PRICELINE EXPRESS deal hotel for 9/16 - 9/19 (thanks for the suggestion re: splitting those specific dates out). Details:
4.5* Times Square - Theatre District for $223/night.
Amenities:
Restaurant, Free Internet, Business Centre, Fitness Centre, No Smoking Rooms.
8/10 Rating
It was the Premier Hotel Times Square, as I suspected :)
Am now going to take a bit of a breather before I tackle the more expensive 09/19 - 09/22!
