"Do hotels that accept this code ask for a company ID? i wanted to use this code at the Park Hyatt Tokyo, but I don't work for General Electric."

"I use corporate codes all the time and never get asked. I shouldn’t be using them but, hey, it is what it is. The risk is you get that front desk agent (or even manager) who goes “I see your with the Coca-Cola rate, can I have your corporate Id please”? Has never happened to me yet but it is a risk. So book accordingly."

"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)."
