"Kroger's Marriott code KRO is a major grocery retail corporate code. No FlyerTalk thread discusses KRO verification incidents. Kroger has 500,000+ US employees making ID verification impractical. Grocery retail corporate travel primarily occurs at select-service properties (Courtyard, Fairfield) near distribution centers and regional offices — property types that essentially never verify corporate codes. hotelcorporatecodes.com lists retail codes as "low enforcement" overall."

"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."

"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."
