"I use a corporate code and never been asked to provide ID…. I feel like it depends on the property and the person working lol"

"In North America I've been asked a single time in the 15 years I've been using Corp rates (for a few years I'd use them on multiple stays per week). My trick is to approach the counter in a friendly way, ask how they are doing, maybe ask an easy question about the hotel (where's the gym?) and connect with them (boy it's hot out there today!) They are happy to have met you, it is a pleasant experience, and you go on your merry way. I'm also Titanium for life and currently have Ambassador, but I've done this when Gold and Platinum. For that one time they asked I said I had actually just started and didn't have my business cards yet, but should have them for my next stay and they let it go. I was never asked by that hotel again (Courtyard Bellevue on an Accenture rate.) Doing a mobile check-in will also shorten the time spent. Just have your ID and card ready to speed things along."

"It’s about 80/20 for me. 80% of the time I still have to go to the front desk. I’ve asked the front desk folks, and they always say “our property has a policy to not allow mobile check-in”… I guess Marriott allows this at the property’s discretion. One property said they don’t want the guest to get stuck with full charges if they end up having travel issues and mobile checked-in the day before."
