"GE International Hyatt code (13307) follows Hyatt's standard verification pattern for major industrial codes. FlyerTalk documents Hyatt as "notorious for checking ID, especially at Park Hyatt." GE International implies non-US travel, concentrated in Asia/Europe where Hyatt verification is highest. Park Hyatt and Grand Hyatt in global business centers regularly encounter GE employees and know what GE badges look like. Hyatt Place and House: essentially never check."

"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)."

"I have a reservation in DC this weekend (11/14) and the LTO110 code showed up for it when I rechecked availability/rates. A call to GP customer service verified the rate and dropped the price 10% below what I'd previously booked. It does require a bit of clicking about on the site, but it's there. Under 'reservations', hit 'specials & packages', then the 'hyatt special offers' tab. The link to the LTO110 rate is the fourth one down."
