"FlyerTalk has a dedicated thread on FedEx corporate hotel rates. One commenter noted having "permission from FedEx's head of security" but the documentation was never actually produced at check-in. HotelCorporateCodes.com rates Marriott FED as "Sometimes." A key concern: FedEx reportedly monitors hotel usage volume with Marriott, and inflated usage could affect their contract negotiations. One user warned that using the code risks getting charged the full rack rate at full-service Marriott properties."

"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."

"We know what the various Deloitte, EY, PwC, Google, Meta, etc badges look like. If you work for the company, it’s not a problem to verify that you work there. We do this for the random people that say they work for Deloitte, when in reality, they just refill the vending machine at a Deloitte office."
