"AON's Radisson code (55321) is for the consulting and insurance brokerage firm. Radisson's general franchise-based enforcement policy: "Most Radisson corporate codes do not require ID verification." AON has a documented Hyatt code with Medium risk — but Radisson's franchise network applies far less consistent enforcement. No AON+Radisson specific incident documented. The Americas Radisson properties (now Choice Hotels) have even lower enforcement than the European-managed properties."

"There is the delightful CARLSONF family & friends promotional code, which means the equivalent of EUR 80 at any hotel with availability. You need to mention the name and work location of a Carlson group employee."

"I leverage my work corporate rates for my leisure travel. I've never been asked for employee ID as a result — they just verify the rate code at booking."
