Last year I did a Platinum Challenge and passed, and have been Platinum with Marriott for over six months. I only completed 37 nights with them, and I'd need 75 to maintain Platinum for another year. However, when I log into my account it still says Platinum, and still shows my 37 nights earned 'this year'. Have they simply not reset for 2013? Or do they not run January to January? I wouldn't mind doing enough nights to maintain Gold, but I won't bother if they won't count. Frankly I prefer the IHG reward program Priority Club; easier to keep and maintain status, and better rewards. For reference I used to do about 146 nights in hotels per year, but after a company relocation I suspect it will be closer to 90-100 this year.
