I called today because I had 95 elite nights, which means 20 nights about the last threshold of 75 nights. However, only 5 nights rolled over because the equivalent of 15 nights had rolled over the year prior. Marriott's policy is to roll over nights only once. So, that means that Marriott's best customers create a deficit by staying with Marriott beyond the minimum needed for qualifying. I should have stayed those extra nights at another brand and build up elite status. I'll know better next year.
I stayed exclusively at Marriott in 2012 and stayed approx.95 nights. My account now registers 0 because they say when they deducted my 25 rollover nights, the other nights don't count. Think I will start staying at Hiltons' where when you are Platinum, your status stays intact.
I don't see why your other 20 nights (95 nights - 75 nights for Platinum elite) didn't count unless those 20 nights were rollover nights from 2011 to 2012 (then it won't count). I had 158 nights last year and 18 were rollover nights which means that only 140 nights (158-18) will count. Subtract that from 75 nights since I hit Platinum and I have 65 nights alone at the start of this year. I stayed a few nights already and had some bonus nights (for hitting $3K spending) counted. I'm now Platinum within the second week.
I'm not a regular Hilton person, but I don't recall it ever having rollover nights. If that's the case, this means even if you hit 200 nights a year it won't rollover next year. Meaning, you start at 0 (zero) nights. Marriott at least counts the previous year's nights. Unless you can stay so many nights that your rollover carries over for two years, I don't see why that's a problem.
I do see posts from other members saying they still show 0. My rollover nights posted early last week and if you do have qualified nights from last year, you should see them posted soon as well.
