Its going for the Uk Centurion also at the end of the year I think. Great shame, but its a decision for Mandarin Oriental - they clearly don't feel the benefits are there. For my part, I have used it a few times, but it wouldn't make me go back to the hotels outside of the programme (I don't know how others feel).
I'm now really worried Starwood Plat will slip to gold - that for me is the number one reason to have Centurion (other than having it for its own sake obviously)
