"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."

"Cisco's Radisson code (27810) is a secondary Cisco corporate code alongside verified IHG and Hyatt codes. Radisson's general enforcement pattern: "Most Radisson corporate codes do not require ID verification at check-in." The Americas Radisson properties (operated by Choice Hotels since 2022) have further reduced enforcement consistency. Cisco's tech employee demographic is well-served by IHG and Hyatt codes in Silicon Valley markets, making the Radisson code less critical and less monitored."

"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."
