"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."

"I use my corporate rate all the time and was never asked for proof until my last stay. My work ID doesn’t identity the company since it provides building access so they accepted me sending an email from my @company.com domain on the spot"

"Just call the 1-800 reseversation center and asked for "Oracle" or which ever corp rate you are interested in. Res agents won't give out the code, but they will book under the rate you have asked for and won't ask/challenge your eligibility"
