"Hyatt corporate codes as a category are documented on FlyerTalk: "You'll read countless stories of folks getting their IDs checked, and in some cases finding out that they needed either a special company letter or someone from the company to fax in their reason for staying there. There have also been some asks such as needing to have your company badge on hand." No BMW-specific Hyatt denial case found, but Hyatt is noted as stricter than Marriott overall."

"We just have to book under our corporate rate in Concur regardless of rate. Example in Columbus, OH our 2 preferred properties are Hilton downtown and Hilton Polaris those rooms can be $400+ a night. If I book at the Hyatt House at $199-$225 also part of our general corporate rate off BAR it will tell me I’m out of compliance for not booking our preferred hotels even though they are more. I override this all the time but that’s how it works."

"Just FYI, the Hyatt Regency Kiev does require Corporate ID upon check-in. My corporate rate is 220 EUR instead of 410 per night and they were quite insistent on getting the corporate ID. Good thing I had it with me."
