"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 rate I’ve booked under for a large big tech company allows for personal use, and I’ve checked in numerous times with my family in locations where my company doesn’t have an office. I can count on one hand the number of times over the past decade (lifetime platinum) I’ve been asked for proof of employment with that company."

"I didn't say that it was a for sure thing where you wouldn't be asked for ID. I can't speak for every hotel as each hotel is independently owned and operated (thank the franchise model), but at our hotel, we do send prearrival emails to those who we suspect may have booked the rate program when they most likely do not work for that company. As I said, anyone can book that rate if they know the corporate code. People can even book our employee discount if they know the code. But it's up to the hotel to follow procedures at check-in to determine eligibility."
