What is your experience with automatic (unasked) room upgrades as a PP Elite? It has been bit of a curate's egg for me as I usually have to ask for it explicitly.
In contrast, as a Spire Elite member in IHG, I am more or less assured of an automatic upgrade every time I check in without having to ask for it. It may not be the costliest suite but the upgraded room is at least 1 and many times 2 levels higher than the one I am paying for.
Now that I have an Ambassador, I may have more luck starting this year but this does remain one of the mysteries with the Marriott program for me. Thoughts?
