I checked into a FS Marriott in Florida the other night. I noticed some bugs roaming around, and went back to the front desk to change rooms. She said "I will upgrade you to a suite because of the bugs". Non-antagonistically, I asked her why I didn't get an upgrade anyways at check-in, for being a Life Plat and for a single night stay, checking in at 11:00 PM (little chance they're going to sell a suite at midnight for one night only). She looked at me and said "oh, you were upgraded to the concierge floor before. We consider that an upgrade".
I gave a wry smile, shook my head and headed back to the elevators. Maybe I'm wrong, but for Golds and Plats, getting a concierge floor room isn't an upgrade since concierge access is a basic status privilege. Right?
