AAA

The AAA Diamond Program is one of North America’s oldest continuous hotel rating systems, operating for more than 88 years. Over its long history, it provided travelers with professional, reliable quality assessments long before online reviews or travel websites existed. AAA’s original printed TourBooks served as essential travel guides for generations of motorists, offering trusted listings of inspected hotels and restaurants. The program helped shape hospitality standards by establishing clear expectations for different quality tiers. Over the decades, it has continued to evolve with traveler needs and industry trends—most recently incorporating scientific ATP cleanliness testing to enhance accountability and transparency. Today, the Diamond designation remains a widely recognized and credible indicator of hotel quality, backed by decades of consistent, professional evaluation.
