"HotelCorporateCodes.com rates Marriott WEL as "Sometimes" for ID verification. Marriott tends to verify more than Hilton or IHG. The SF Marriott properties — near Wells Fargo HQ — were specifically mentioned as properties that cracked down on corporate code abuse. No WEL-specific denial documented in public forums. Business cards have been reported as universally accepted when verification is requested."

"I don't do mobile check-in if I'm wanting to upgrade. I check the app before I go in to see if any suites are available to book during the duration of my stay. If there is I just say "Would it be possible to get upgraded to an available suite with my platinum benefit?". Of course this is typically at the hotel that I stay in about once a month for 3 day at a time for work. The front desk pretty much knows me and know that I am fairly low maintenance."

"I wouldn’t mind that at all. Credit Card companies have super weak security and it’s very easy to defraud them - they just pay our money back, and counts that as losses so we’ll sure up about it and keep using the cards What I mind is that the mobile check-in is basically a lie. Marriott is deceiving me. Random hypothetical people that might or might not stole my credit card are not. Hilton works just fine btw"
