"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."

"I get randomly asked for my id if I check in at peak times, if it’s late or super early morning they just let it go. I’ve showed my corporate email on my phone for proof before"

"I was referring specifically to a corporate ID. I know international properties ask for passport. What I mean is that I have always been asked for both my corporate ID and personal ID every time I've used a corporate code at an int'l property."
