So, last year in 2011 I had 62 nights. Marriott Rewards rolled over 12 so that was my base in 2012. Now I'm at 73 nights and can easily get to 75, but I wonder if they will give me platinum and roll over 25 nights (above the 50 to be gold) or if I just become platinum and nothing rolls over? I see very little extra value between gold and platinum and would likely choose to hold my nights below 75 if I'll get that big rollover by staying at Gold.
Any insights?
