"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. ."

"I have been a Platinum for a few years (which implies I frequent Marriott properties on a regular basis) and up until tonight was NEVER asked for any id to justify a corporate rate or discount (I legitimately use a few corporate rates I am entitled to and AAA rates)"

"I can say, with absolute certainty, I've never been asked for a Corporate ID: only a business card. Despite working for a company towards the top of the F50 list, I am a remote employee. Remote employees are not given IDs in our company. When I do have to go to the office, I need to get a guest ID."
