AAA

The AAA Diamond Program has been evaluating hotels for more than 88 years, making it one of the longest‑running hotel rating systems in North America. Over that time, AAA has continually refined its inspection criteria, trained generations of professional inspectors, and built an extensive database of evaluated properties. The program has evolved alongside traveler expectations and industry standards—most recently with the addition of ATP cleanliness testing. This long history gives AAA deep expertise in hospitality evaluation and has established the Diamond designation as a widely recognized and trusted indicator of hotel quality.
