Bayer at Marriott Bonvoy

"hotelcorporatecodes.com specifically categorises the Bayer/MLM code as "Rarely" for ID checks — the only entry rated below "Sometimes" in the pharma-sector Marriott codes. The MLM ticker does not correspond to an obvious company name, limiting its public notoriety. Pharma codes as a category are generally Medium, but Bayer's specific code consistently surfaces in the "low scrutiny" tier on aggregator sites, consistent with a large but relatively travel-light pharma footprint compared to consulting or finance."

"I'm guessing so, but I'm not a Marriott employee. Also, to answer some of the other questions floating around here, I have never been asked to produce my work ID when checking into the hotel that I booked using a corporate rate. I travel half a dozen times a year."

"In North America I've been asked a single time in the 15 years I've been using Corp rates (for a few years I'd use them on multiple stays per week). My trick is to approach the counter in a friendly way, ask how they are doing, maybe ask an easy question about the hotel (where's the gym?) and connect with them (boy it's hot out there today!) They are happy to have met you, it is a pleasant experience, and you go on your merry way. I'm also Titanium for life and currently have Ambassador, but I've done this when Gold and Platinum. For that one time they asked I said I had actually just started and didn't have my business cards yet, but should have them for my next stay and they let it go. I was never asked by that hotel again (Courtyard Bellevue on an Accenture rate.) Doing a mobile check-in will also shorten the time spent. Just have your ID and card ready to speed things along."
