"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."

"I dont even have a corporate ID or badge lol, i started my job remote and I’ve never even been to a corporate building yet despite having made five or six business trips in the last two months and never been asked to show proof i work for the company i work for. So im gonna place my bet on no, altho if you have a family with you they might question whether you’re actually on a business trip."

"I stayed under a corporate rate at six different hotels in Japan over the course of two weeks, I did have a company name badge with me in case anyone asked, but I was never asked to provide proof. Properties were Sheraton, St. Regis, Westin, and Marriott."
