Visitors enter the building under a textured and faceted grand glass canopy. East of the hotel tower is a casino, retail area, and dining, bar, and lounge space. West of the towers is a 1,800-seat theater with a layered, three-dimensional façade. Just past the theater is a three-level conference center.
