"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 mean, you can book the rate, but 100% PH Tokyo requires proof of employment. I had to email from corp domain and provide a business card (Dec 2022). If you show up and can't provide proof of employment, either you'll be paying a very expensive full price for your stay, or they'll invalidate your reservation."

"I would strongly advise the use of a corporate discount code that you are not entitled to. No doubt that IBM would receive a summary of all reservations made under their code and at what property, and no doubt lurkers on here would be well aware of unauthorised use. In essence it amounds to fraud and I would not want IBM or Hyatt's legal department against me."
