"AAA (alt 2) Hyatt code (15985) is another secondary AAA membership discount code at Hyatt. AAA rates are publicly advertised and require only showing an AAA membership card. FlyerTalk documents: another reported being asked only twice in 70-80 stays. AAA rates are typically 5-15% off, reducing hotels' incentive to verify. The secondary code designation suggests it may be for specific Hyatt properties or booking channels with even lower enforcement than the primary code."
