Two years after the originally intended opening date, Caesars Palace Las Vegas has again turned its attention to the 668-room Octavius Tower, which now will debut Jan. 2, 2012. Rooms in the resort's sixth tower opened for bookings yesterday. The final piece in Caesars' $860 million expansion project, the new luxury tower will have a private entrance, a separate hotel lobby, and direct access to the resort's Garden of the Gods pool complex and gardens. Guest rooms will have modern décor and feature marble floors and dark wood furnishings, as well as 42-inch flat-panel HDTVs. An iPad/iPod Touch app will allow guests to communicate with room service, housekeeping, reservations and front-desk services. The resort, which currently has 3,348 rooms, postponed the tower's original opening until market demand improved.
