"BMW's Marriott corporate code does not have specific community-documented denial cases. FlyerTalk's general corporate code thread warns: "Every hotel has the right to ask for identification that associates with the corporate code — but very few actually do." BMW is a premium brand with a recognizable code, moderately identifiable to hotel staff. European properties — especially in Germany — carry a higher verification 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."

"My employer does not have a corporate rate but when I'm consulting for a company that does, I use theirs. I've only been challenged for identification once. In that one situation I explained the consulting arrangement, and the desk clerk accepted it without a badge or business card (neither of which I had anyway)."
