"Legg Mason's Marriott code LGM is a financial services code. Legg Mason was acquired by Franklin Templeton in 2020, meaning Legg Mason-branded employee credentials may no longer exist — similar to EDS/HP. Baltimore-based operations (where Legg Mason was headquartered) mean nearby Marriott properties may still have residual familiarity with the account. Finance-sector Medium calibration applies. The post-acquisition brand change adds uncertainty for hotels attempting to verify affiliation."

"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 have been asked to show some proof couple of times. I normally show my corp id but credit card with employers name on it has worked, too. As would probably just showing my laptop with employer e-mail account or whatever. My impression has been they are happy with just about anything that proves I'm working for the company whose rate I use and why wouldn't they."
