"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."

"Just wanted to let you know that I tried using this code at Hyatt Regency Istanbul, and the guy asked me for ID. I explained that I was a contractor, but he wouldn't buy it and requested further verification. I told him to just charge me the regular rate, and I would get reimbursed. It was only a 25 euro difference per day."

"I can understand wanting to maintain rate integrity, however, I find this to be a bit over the top. While I don't know the particulars of this rate, Louis Vuitton is a global company with employees presumably all over the world. How the hotel would have the resources to verify every employee seems a bit far fetched, especially with huge companies like IBM. Also, does this rate extend to all employees of Louis Vuitton or just traveling executives? I cannot imagine that they would be able to verify that Sally Sue (who likely does not even have a corporate ID) working at the South Park Mall store in Charlotte, NC is indeed an employee."
