"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."

"Boeing's Radisson code (20494) is a secondary Boeing code alongside the Marriott code (BWG rated Medium). Radisson's franchise network applies far less consistent enforcement than Marriott. Boeing's major travel markets (Seattle, Chicago, Charleston SC, St. Louis) are primarily Marriott/Hilton-dominated, making the Radisson code a lower-frequency option. Radisson's Americas properties (now Choice Hotels) have minimal verification infrastructure."
