AAA

More than 23,000 hotels have passed AAA inspections that include ATP surface testing. This figure aligns with the total number of AAA Diamond‑designated hotels, as ATP testing is now a standard part of every AAA hotel inspection. When travelers see the Inspected Clean indicator on a hotel listing, they know the property has undergone scientific cleanliness testing using methods also applied in healthcare and food‑safety environments. The Inspected Clean program was introduced in response to heightened traveler concerns about sanitation and has since become a permanent element of AAA’s hotel evaluation process, ensuring consistent, science‑based cleanliness verification across all Diamond tiers.
