"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 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."

"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."
