The Waldorf=Astoria Collection is a collection of what the Hilton Worldwide considers to be its premiere, most luxurious and most identifiable hotels and resorts. In January 2006, Hilton Hotels, Inc, announced it would launch a luxury brand called The Waldorf Astoria Collection, branded after the Waldorf-Astoria Hotel in New York City. As of April 2007, there were 4 properties -- the Arizona Biltmore in Phoenix, La Quinta Resort & Spa in La Quinta, California, the Waldorf=Astoria in New York and the Grand Wailea Resort & Spa in Maui, Hawaii. Later in 2007, the Qasr Al Sharq in Jeddah, Saudi Arabia was added to the portfolio. The next property to join the portfolio was the Rome Cavelieri, a rebranding and upgrading of the Cavalieri in Rome, Italy in early summer 2008. During the fall of 2008, three Florida hotels, located in Boca Raton, Key West and Naples, were also added. In July 2009, the Dakota Mountain Lodge opened in Park City, Utah. It is the first ski resort to join the portfolio.
