"AAA (alt) Hyatt codes (17500 and 15985) are secondary AAA membership discount codes. AAA rates are publicly advertised membership discounts — not confidential employee benefits. FlyerTalk's dedicated 'AAA card – Do hotels check?' thread documents: 'One frequent traveler staying 1-3 hotels per week was asked for the AAA card at about 10-15% of hotels.' AAA membership cards are easy to carry and present. These alt codes share the same low-risk profile as the primary AAA Hyatt codes."

"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"

"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."
