"Pepsi 20937 is confirmed in Hyatt code directories. FlyerTalk user Colin stated: "US & MX hotels never check, in my experience" for consumer/FMCG brand codes. Pepsi is headquartered in Purchase NY with heavy Hyatt usage at mid-tier domestic properties (Hyatt Place, Hyatt House) — the exact brands identified as having the rarest verification rates. Consumer packaged-goods brands present the same ambiguous franchise/bottler affiliation challenge as McDonald's, making challenges impractical."

"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've only used corporate codes twice. Was never asked for anything at Hyatt Regency Waikiki, but was asked for proof of association at check-in at Park Hyatt Tokyo (which I did provide)."
