"Oracle's Marriott corporate rate is GDS only and cannot be used for direct consumer booking. Multiple FlyerTalk threads confirm this restriction has been in place for 3-4 years due to Oracle's close partnership with Marriott (Oracle even owns a Marriott property). Any hotel booking that bypasses the internal portal is essentially unauthorized use of the rate, raising the verification risk significantly at luxury/full-service Marriott properties."

"Corporate code - never once and we’re in the 200+ night a year arena. Gov discount / AAA- always be prepared to show ID Edit: reading comments and I recalled the Ritz in Singapore asked - but we had a corporate package to receive. Also our rate was maybe $300 and the normal rate was about 3 x that so perhaps that’s a part of the equation. In any event if you don’t have ID just shoot them an email from your corporate address"
