"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."

"Last year December, two stays. Radisson ARN Skyline. No form was asked. Code RHGRFNF still works, checked a week ago."

"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."
