I have been staying at one the the Hilton's Middle East properties for 5 months and plan to stay a lot longer. I have also referred them 4 work colleagues who have stayed at the hotel for stays of 1-2 months on the same deal.

I negotiated a reasonable deal for a standard room and as a Diamond HHonors member, I get automatically upgraded to a deluxe room.

I am keen to move to a suite but they are asking for a rate that is unaffordable (almost 75% extra of what I am currently paying).

My negotiations have been directly with the hotel but I was wondering if there was any merit in asking the HHonors Diamond desk to intervene. They may, for instance give me a decent rate if I use some of my points.

I would have thought that my loyalty would have been rewarded with a better room by now, but I am prepared to pay a bit more if that's what it takes.

Any ideas /suggestions would be warmly appreciated.
