"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."

"I mean, you can book the rate, but 100% PH Tokyo requires proof of employment. I had to email from corp domain and provide a business card (Dec 2022). If you show up and can't provide proof of employment, either you'll be paying a very expensive full price for your stay, or they'll invalidate your reservation."
