Other than the basic Marriott Suites, Renaissance and JW? No dice. The partnership with MGM ended years ago (again, I don't remember when, but it was quite a while ago).

Regarding earning at the Ritz Carlton, I used to spend a few nights every year at the Buckhead Atlanta property and remember always earning points there (90s); I do not recall whether or not I earned at Marina Del Rey which again was a property I spent a fair amount of time at. I'm guessing since I stayed there and stopped I was earning there. I don't remember if it was hit and miss; but Socrates would certainly know and it was just too long ago and too many stays ago Other chains have found that their top tier properties do just fine in their rewards program but MR for whatever reason keep theirs out.
