"Hyatt Senior Citizen rate (17497) is a leisure discount, not a corporate code. FlyerTalk confirms: "World of Hyatt Senior Discount — no company ID required, just age verification at some properties. Front desk may ask for ID to confirm age." This is a publicly advertised promotional rate, not an employee benefit code. Age can be verified by any government ID. Risk of rate-challenge at check-in is essentially zero."

"Strangely enough I have never been asked for Corporate ID, even internationally, at either Hilton or Starwood when I book using a corporate discount code. Yet another reason why Hyatt is a distant fourth in my hotel choices."

"I’ve never been asked at Hyatt but have at Marriott - specifically in Tel Aviv (which I was staying at as there were no Hyatts when I was there). You can also be working FOR a client whose company code you are using so it makes the idea of a company code and the verification rather meaningless."
