"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. ."

"Bank One's Marriott code BOB may still exist in Marriott's GDS system following the 2004 acquisition by JPMorgan Chase. JPMorgan has a separate Marriott code (JPM). Legacy acquired-company codes are practically never verified as the hotel has no way to confirm employer identity for a company that no longer exists independently. Risk for legacy codes is negligible."
