"FlyerTalk documents Samsung codes as remarkable — one user reported 70% off at the Grand Hyatt Hong Kong. HotelCorporateCodes.com rates Samsung as "Sometimes" for ID verification at Hyatt. Hyatt's general pattern: Park Hyatt checks most frequently, Grand Hyatt and Regency occasionally, Hyatt Place/House rarely. Hyatt is described as "notorious for checking for ID," especially internationally. One user documented 50% ID check rate across Hyatt stays in 10 countries, mitigated by self-printed business cards which "worked 100% of the time.""

"I was asking who was eligible to use OUR corporate discount when the GM volunteered this information. Management is way more visible at the (rather small) PHT than at larger Hyatts. I know I'm highly likely to run into the GM or his chief assistant during every stay, especially since I'm usually there for at least a week. Hence, I often hang on to my non-urgent questions until I see them. Might as well hear it from the source!"

"I know that my former employer, a very large non US-based multinational company (I am not sure if US-based companies are more careful due to liability issues etc.), doesn't really care whether or not the person using its hotel corporate rates (worldwide agreements with 2 different large hotel chains) is an employee. In fact the company secretly hopes that others (non-staff) use its corporate rate. The name of the game is volume and the more the volume the better the company's leverage on the hotel. That is why it is usually the hotels who insist on asking for company IDs or business cards (which I suppose anyone can print ... though I am not suggesting that FTers should go this route)."
