If you eat out or stay in hotels with any regularity, there’s a chance that you’ve eaten or stayed at a AAA Diamond Rated property. With around 60,000 establishments across North America and the Caribbean, the AAA Diamond Rating system is a trustworthy source for travelers to find  hotels and restaurants that suit their budget and preferences. Yet for the uninitiated, AAA Diamonds might at first seem confusing.

Unlike many other rating systems that weigh an average based on customer reviews, AAA Diamonds are based on price range and standards set by AAA inspectors. They connote cleanliness, quality and comfort across the board – no matter how many or how few Diamonds are assigned. If an establishment does not meet a certain level of excellence in these areas, they are removed from the list of AAA Diamond Rated properties entirely. Any Diamond is a good Diamond.

Professional AAA inspectors are fastidious, exacting and discreet. They have a background in travel or hospitality, and are experts in the field. AAA inspectors conduct unscheduled evaluations of AAA Diamond establishments as well as AAA Diamond hopefuls. Inspectors only identify themselves when absolutely necessary, like when they need access to spaces that guests don’t normally see. For potential Five Diamond establishments, complete anonymity is maintained.

AAA has conducted field inspections for over 80 years, and periodic reviews and adjustments make sure their recommendations stay up-to-date. AAA Diamond standards change periodically to align with industry trends and guest expectations. Ratings are updated every five years, taking industry trends, focus groups and member surveys into account. Consequently, AAA inspectors typically visit over 80 properties in a month.

  • The articles were very helpful. But nowhere did you mention “cleanliness” in any of the ratings. Why is that? Anna Ievolo

      Hi, Anna!
      Any amount of AAA Diamonds connotes a high standard of cleanliness, quality and comfort. Establishments that do not meet these standards are not given a AAA Diamond Rating.

    I remember years ago AAA had a star rating system. There was a sign near the hotel sign or parking lot/driveway entrance saying AAA approved. Is this the case with AAA diamond ratings also?

    • Sarah H.

      Hi, Jeffrey!
      It is! You’re most likely remembering the AAA Diamond Rating system itself, since AAA does not use stars (it appears Australia’s version of AAA does, though). AAA Approved or Diamond Rated establishments often (but not always) display signs stating the AAA Diamonds they hold.

  • I wasn’t impressed with the diamond rating system, especially, but not entirely, where the restaurants are concerned. The system appears more focused on cost than quality. A simple hamburger can be reasonably priced & juicy, or as dry as a shoe sole, having more to do with the quality of the cook than anything else. A low-priced motel can have lumpy beds or comfy ones. So I’d be more impressed with quality ratings than cost references.

    • Sarah H.

      Hi, Louisa!
      AAA Diamonds do measure cost, if only because more luxurious things tend to be costlier. In the past, AAA restaurant reviews were more interested in ambiance and service, but in recent years the actual food has been given much more weight. All AAA Approved and Diamond Rated establishments have to meet a base line of quality. As the amount of Diamonds goes up, so does the luxury of an establishment.
