Room Upgrade
When you check in, we’ll upgrade you to our best-available guest room at no additional charge. Not available for suites at Marriott Vacation Club International. For Residence Inn and TownePlace Suites, upgrades from studio to 1- or 2-bedrooms are not guaranteed. For The Ritz-Carlton, Club Level and suites are excluded.

Of course the first question is how do you know if you are getting the 'best available room'.

As noted previously, after talking to managers there always seems to be a better room available and for some 'reason' you were not given it.

Originally the PP program used to state that PP would receive 'Marriott's best service'. In recent years it seems they removed this language.

Given that PP's can only see our benefits online I can say they essentially just repeat the Plat benefits.

Despite all that, when a property does recognize you as a PP it can be quite impressive, in my experience that is only about 10% of the time. The rest of the time you might as well be a Plat. So there is a huge divergence between how a PP is treated when 'recognized' at a property and at properties that don't seem to know PP exists.

So if as a PP you have those 10% experiences in your head, you might come to 'expect' getting a room upgrade unless it's an unusual experience.
