Nothing wrong at all with your situation being unsatisfactory. In fact, i feel like you've been using a wiretap on my own life! I've given this same rant and multiple others to anyone that will listen. HA!
I've made a few comments throught the FT boards on different threads at just how disappointing the MR program has been since i made PP.
In a nutshell - when i was platinum, i took everything with stride and upgrades were cool, points were cool - etc. it was just a "nice status". But since Marriott took the action to designate me with a secret status of PP (again - i didn't ask for it and none of truly know how you qualify, so MR made the distinction for me/us!) ... i have seen nothing different.
And that is a valid 'gripe' to point out. You can't give someone a special tier and not expect something to change. They've now made my rollover nights change - and that is the only variable i've seen different since PP. No new benefits, no new points, nothing. I actually found an email to MR finally get received and i had a very productive conversation with a big shot in the MR dept and she was very courteous and finally "listened". unfortunately - no change. Your boston situation is all too familiar to me - and i'm at 159 nights in a hotel (head on pillow) and being not given anything finally made me ask her to just drop me back down to a Platinum, so i wouldn't expect too much anymore. And then she said she couldn't - and that was equally confusing.
Anyway - sorry for the novel here, it's early AM and i'm on a ORD layover eating bad breakfast tacos and killing time.
But i wanted to tell the OP, that i feel his pain and i don't think he's whining, but unfortunately, any attempts here on my side have gone futile to remedy anything.
Good luck!
