I've been Hilton Diamond for a few years. The past year I had an assignment which took me to obsure town in Germany and I spend several months in a local hotel...no points

Now, with the holidays in front of me, I may not even qualify for gold. The project is over, what are the chances that Hilton will understand my delima and extend my Diamond status? any suggestions before i contact them? Should I wait until the year is over?
