Which can be useful if they don't cap the highest possible room you can upgrade into, since the benefit isn't explicitly to the best available suite, but just to an executive room or suite, and it isn't to 'an executive room if no suite is available' but rather an executive room satisfies the minimum condition of the t&c.

But the 1/2 level upgrades are especially problematic at hotels that identify tons of unique room categories.

Still, executive room is problematic as well eg at the Mark Hopkins where it's been reported that they consider a room with a fax machine to be an executive room.

So even with the T&C there's plenty of room for hotels to play apparently and it comes back to how each individual property treats RAs. We should give business to those who reward loyalty, and avoid those which do not. I don't really like having to fight for the benefits anyway.
