"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."

"Radisson Blu New World, Shanghai — No questions asked and no upgrades or breakfast. Room was fine, no issues at all with the corporate rate."

"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."
