The rebranding/renaming should be complete by Christmas with the casino, retail and lobby renovations completed by the end of 2013.
'The Quad will bring a renovated casino, check-in desk, dining and retail outlets to the aging hotel so, basically, expect an entirely new resort. Except for its dealertainers and car collection. Pulse of Vegas says those will stay around. And, side note, we feel much more comfortable using the "r" word in conjunction with that stretch of Strip real estate now."
'The casino floor will expand an additional 15,000 square feet engulfing the former Imperial Palace porte cochere and a nightclub and gift shop. The first phase of casino renovations will include 35,000 square feet, including the expansion, and is scheduled for completion in the spring of 2013. The second phase will include an additional 30,000 square feet of gaming space with a centralized promenade bar featuring state-of-the-art integrated audio-visual technology. This phase is scheduled for completion in late 2013."
