20 Times Square, or 701 Seventh Avenue, is located on the northeast corner where 47^th Street and Seventh Avenue intersect.  When finished, 20 Times Square will host a variety of functions, including nearly 75,000 square feet of premium retail space, 30,000 square feet of multi-function entertainment spaces (including a premier nightclub and a 7,000 square foot rooftop terrace that overlooks the heart of Times Square), a 150,000 square foot high-end hotel with 452 guest rooms (to be branded as a Marriott Edition, the collaboration between Ian Schrager and Marriott Hotels), and an 18,000 square foot hi-definition LED sign, rising 120 feet above the bustling streets below and wrapping around both the 47^th Street and Seventh Avenue facades.
