"Stanford University's Marriott code 349097 is an academic institutional code. University codes at Marriott select-service and full-service properties are rarely scrutinized. Stanford's Silicon Valley presence means nearby Marriott properties are familiar with the code, but academic corporate rates are not high-value enough to trigger enforcement. No verification-denial cases documented in any public forum."

"I used to China often for work and book directly. I’ve never been asked, if you have a sticker or they can see something with the company logo they assume you work there. I’ve only been asked in Korea and was a hot mess until a manager stepped in."

"I think the last time I was asked for proof was in a JW Marriott in Beijing. I have never been asked in the US or Europe. Without a business card or ID, you may have an issue. Maybe you can contact the hotels in advance to see what info they need. I don’t remember if LinkedIn is available in China so I would talk to your Corp Travel team to see what they can do. Good news is that hotels are so much cheaper in China compared to ROW right now. ."
