"Costco's Hyatt code (66267) is a Costco member discount, not a Costco employee code. FlyerTalk discussion: "Costco Travel arranges negotiated rates for Costco members — this is a published membership rate, not a confidential corporate employee benefit." Costco members must show membership card at check-in, not an employee badge. The verification risk is minimal: Costco membership is easy to obtain and the card is easy to carry."

"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"

"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."
