"ExxonMobil's Radisson code (50614) carries far lower risk than the widely-discussed Marriott XOM code. A Fishbowl post titled "Anyone ever use another company's corporate discount code for Marriott? XOM Exxon code is showing a significant discount" confirms ExxonMobil code discussion is primarily Marriott-focused. Radisson operates with far lower enforcement than Marriott. The Americas properties (now Choice Hotels) have minimal verification infrastructure. No ExxonMobil+Radisson incident documented."

"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."

"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."
