"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've been given codes for several chains from family/friends who are entitled to have them. All have assured me they have never been asked to provide company ID when checking in. In fact I was told they give the codes out to visiting clients who won't have ID anyway."

"Same- we stay at a very large Jw often just for a quick get away and have gotten to know a few of the staff. We’ve checked in numerous times and have been told there aren’t any upgrades - I’m Platinum. No worries, we’re just happy to be on vacation for a few days. Shortly after we’ve seen a specific front desk agent that is always friendly with us and she has upgraded us (yes, after we’ve checked in) at least three times…. And mentioned as she’s doing it, “idk why they didn’t upgrade you…. “ we never asked her since we were already checked in and we’re fine with the regular room. But certainly, a suite is a nice upgrade and very much enjoyed."
