I will always travel a lot for work, but it is unlikely that 2013 will be the same as 2012 where I made it to gold by April without the help of a Marriott credit card.

My impression is that with the ability to rollover nights, Marriott status is the easiest to keep even if your stay frequency varies greatly.

I'm at 85 nights now and will most likely be over 120 by year end, so that puts me on a good footing for making Platinum into 2015 right?
