"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)"

"HotelCorporateCodes.com rates the Marriott DIS code as "Sometimes" for ID verification. No dedicated forum thread found specifically discussing Disney corporate code verification incidents. Disney has 140,000+ US employees and the code is widely circulated. One FlyerTalk user noted that a retired employee who disclosed their retired status was never asked for ID, suggesting properties prioritize rate code volume over strict verification. FL Marriott properties near Orlando HQ are most familiar with the code."

"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. ."
