I’ve seen a couple of threads but I’m not finding a definitive answer.

Does Marriott work on a calendar year? I ended 2010 with 47 nights and my plan is to rollover 37 nights and get platinum this year. I have the Marriott CC so I get 15 nights just for having the card which should give me immediate gold in 2011.

Looking at my account it still shows 47 nights this year and 3 more to get gold. I don’t want to hit gold based on last years stay since I won’t have any carryover and I’d have to do all of the nights to reach platinum.

Does anyone know how this actually works with Marriott?

Thanks in advance.
