I remember an article from a while ago where Arne Sorenson said Marriott was transitioning to a new tech system where points and activity would post in a 24-hour window from checkout, and other reservations-related features such as viewing hotel floor plans and selecting your room à la Hilton were going to be offered. During my years as an SPG member where I only had to fill one missing stay form in and having to fill countless ones in since the first SPG/MR program merger, I've actually had points post in under two days for a few months and it's been excellent - correct points and all extremely timely. Dare I say it - after all the shenanigans, they're slowly and surely getting their poop in a group.
