The 453-room JW Marriott Camelback Inn Resort & Spa in Paradise Valley, Ariz., has lost its AAA five-diamond rating, according to press reports. The property, which held the prestigious rating for 36 years, was bumped down to four diamonds for 2013. The 76-year-old resort was one of just three resorts in the country to hold the five-diamond rating since the program began in 1976. When contacted by the Arizona Republic, a spokesperson for AAA said, "Based on our published standards, and the expert opinion of our inspectors, the Camelback Inn is accurately rated at four diamonds." Also according to press reports, Shane Allor, director of sales and marketing for Camelback Inn, attributed the drop in ranking largely to outdated bathrooms in the resort's guest rooms. The resort did not update its bathrooms during a $50 million makeover four years ago but has now launched a $10 million project to redo them with modern features including walk-in showers, large showerheads and lighted mirrors.
