"There are countless stories of folks getting their IDs checked when using Hyatt corporate codes, and in some cases they needed either a special company letter or needed someone from the company to fax in their reason for staying there. In most cases, a business card is enough."

"(a microsoft corporate code would work as would any hyatt gov code that adheres to FTR)"

"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."
