You will get your elite nights from your CC at least once per year. So if you received them in November of last year, you should receive them in November this year.

My understanding of nights credited per year will be that you should receive 2 nights credited for 2010 and the rest for 2011.

Two points that may or may not be of interest to you:

1. Right now Marriott is rolling over any "extra" nights you stay beyond renewing your current elite level. Therefore, since you are currently Gold and you get 67 nights credited this calendar year, you should receive 17 rollover nights toward elite status for next year. (Note Marriott's continuing to offer Rollover nights is decided on a year by year basis. So they may not continue to offer Rollover nights after this year.)

2. Marriott uses a 12 month rolling calendar for achieving a higher elite status. Therefore, for you to achieve Plat status, you don't have to necessarily get 75 nights in a calendar year. You only need to get 75 nights within a 12 month window. I'm not sure how or whether Marriott counts those rollover nights toward your 12 month window. Someone else may be more up on that part and can chime in. I would guess they count based on when they are posted to your account, but that is just a guess.
