"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 mean, it depends on the size of the hotel. Having one person on night shift for a Fairfield isn’t uncommon. The better hotels have more people working at front desk even at night simply due to the size and brand. I’d however say though, if the property has been notified of the guest’s check in time in advance, and part of deal of getting into night shift is to check people in at unusual hours like that, then it certainly does not sound right to me that the front desk agent cannot have the meal earlier or later out of that many hours of the shift."

"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)."
