"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 also see a problem where (I know our company has for certain properties) Last Room Available rates which come in at the corporate rate; its not for all properties but we do have a list of those where if there is one room left, they have to give it to us at the corporate rate; other places is a certain number go at Corp rate 1 then it goes to corp rate 2 etc"

"I use MY job's corporate code when booking personal travel. Most companies have a list of which hotels they contract with also allow personal bookings. If you're improperly using a corporate code, the hotel can cancel your booking or change your rate at check in."
