The problem, in my view, with Hiltons current approach is that there is so much ambiguity. How do I know if I'm really getting an upgrade at all? My deluxe room was allocated by the hotel at level 28, now I'm given a deluxe room on level 29 and that would fall within the boundaries of the 'upgrade' yet I won't know it .. or 'feel' it - therefore though the upgrade is real and I always prefer higher rooms, because I don't feel the love in a real way I am more likely to be drawn away to a competitors program if the bennies are perceived to be more regular/obtainable/measurable.
Anyway, whilst paying close attention to the reports as they come in, I'm not going to jump the gun, so far I've always been given an exec upgrade, even overseas, so heres hoping it continues.
