"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 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."

"I am very rarely asked to prove my eligibility for a rate...but they have every right to ask and if you can't produce it, you will be re-rated to the current rate, which is often even higher and there is no guarantee points rooms will be available. Doing online check in rarely helps this as most properties don't actually do online anyway - especially to people who are not returning guests to the property or elite. You are taking a gamble. One that is likely to be fine. But understand you are intentionally breaking the terms of the bonvoy program and if someone really cared, there can be consequences."
