"UBS is explicitly discussed on FlyerTalk in the "Corporate ID required???" thread. One user: "Of the numerous Marriotts I've used my corporate code at in the US and Asia, I was only asked once — at the SF Marriott, because that particular hotel has seen a number of people abusing the corporate discount policy." Another: "Asia is the one place where I have been asked to show ID." A commenter noted: "if Marriott was really concerned about abuse, maybe they should have picked something other than stock ticker symbols as the prevalent corp code" — directly referencing UBS-style codes. hotelcorporatecodes.com: "⚠️ Sometimes," 10-15% discount. Financial services codes at full-service urban Marriotts in Europe (London, Zurich) carry meaningfully higher risk."

"I have a close friend who is a GM at a Marriott property in a fairly large US city (top 25 metro population). Their opinion is basically, "Hey, it's business. I'm not turning away a paying guest if they don't have the right ID." In this person's younger days as a front desk agent, they enjoyed catching people trying to use a corporate rate that the guest was not entitled to. As they became higher up and saw the books, occupancy rates, etc... Corp ID's became far less important than filling rooms."

"I work as a consultant and frequently ask for and use my client's rates (at their insistence, since I will be billing them back). I have been asked for ID maybe one time in 15 since February, when it was announced in this forum that rates would be ID'ed."
