Stayed there for two nights a couple of weeks ago. SPG options were very expensive (both points and dollars) and the FS Marriott looked tired.

I was a bit nervous after reading this thread, but we had a good experience.

Upgraded to a room at the end of the hall with a small seating area, large couch, and a day bed of sorts.

As mentioned in the Wiki, breakfast is now $15/day/person. Can be used outside of breakfast as well (we used for breakfast one day, evening drinks the other). We also got an additional $15 food certificate (I think) as our Platinum arrival gift. We also applied that to drinks at the bar.

Location is good and our limited staff interaction was positive.

Maybe we just got lucky, or maybe they're finally turning it around?
