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

"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."

"I know that my former employer, a very large non US-based multinational company (I am not sure if US-based companies are more careful due to liability issues etc.), doesn't really care whether or not the person using its hotel corporate rates (worldwide agreements with 2 different large hotel chains) is an employee. In fact the company secretly hopes that others (non-staff) use its corporate rate. The name of the game is volume and the more the volume the better the company's leverage on the hotel. That is why it is usually the hotels who insist on asking for company IDs or business cards (which I suppose anyone can print ... though I am not suggesting that FTers should go this route)."
