"Pfizer holds two Marriott codes (4899 and PFZ, with PFE as a third variant). This code duplication reflects Pfizer's large managed travel program. FlyerTalk notes: "In the US and Canada, never asked to show a work badge. Overseas — they tend to follow the rule by the book." Pfizer's dual-code structure suggests a formally managed travel program that may share usage data with Pfizer's travel desk. Risk is medium — consistent with other pharma codes at full-service Marriott properties globally."

"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)."
