I've done this twice at 2 different Marriotts and I have never received the points. I submitted a missing points claim for each and for the first one they said they had no record of me asking for the Green Choice program (even though I had done so through the app). The second claim they responded and said they'd "fix it right away" and the points never posted. So I will never make this "green choice" again. Why should I bother?
