"The Hyatt BP code does not appear in any specific FlyerTalk verification-failure thread. Hyatt's general verification framework applies: Park Hyatt properties are the strictest, with documented cases of guests threatened with rack rate conversion (e.g., "they made me find proof of eligibility or they were going to charge rack rate" at Park Hyatt Tokyo). BP is a high-name-recognition company whose code circulates broadly online, increasing exposure risk."

"I guess I just don't see this. I'm not saying rates never changes, but if it really changed every time someone booked a corporate rate, then the rates would change constantly. I can't say that I see this too often or ever. Also I doubt there's enough people doing this to have a huge effect on overall occupancy anyway."

"I believe it's depends on the hotel. Hyatt will not verify your job status, as long as you made the bookings. However hotel has right to check your badges if they wish. it is very unlikely to harm you, the worse they can do is request you to make full public rate payment. I stayed at Conrad Shenzhen last year with my friend. He kept using his old company's rate code to make Hilton hotel booking even though he has already left. The front desk asked him to verify but he couldn't, so we made full payment in the end, no drama."
