AAA Five Diamond Award is the highest level of the AAA Diamond Ratings System for restaurants and lodgings administered by AAA (formally known as the American Automobile Association). For 2014, just 0.4 percent of the 29,000 AAA/CAA Approved lodgings and 0.2 percent of 30,000 restaurants received the prestigious designation. All properties must first meet AAA’s basic requirements before being evaluated by one of AAA’s inspectors. Once evaluated, a rating of One to Five Diamonds is assigned, based on lodging and restaurant published guidelines for facilities, amenities, and service.
