Yes I agreed, but I need 7 nights more in this year. maybe worth is waiting for next year. I am gold fixed till Feb 2015, I think they move all my nights above gold for next years plus I got 10 nights for credit card in Feb, that mean I will be platinum in Feb or March anyway. Its worth paid for 7 nights this year to achieved PLATINUM?
I'm sure you can't count on this, if you've achieved Platinum status in years past and are only 7 night short of reaching 75 nights goal in 2014, Marriott might just bump you up to the Platinum level. They've done this for me before, but I wouldn't count on it continually.
Maintaining Platinum status and using a Marriott Visa Signature (black) charge card for Marriott stays and other purchases is the best way to maximum points in your reward account.
Another way to take advantage of not only points accumulation but also night stays is if you have the occasion to travel with non-Marriott members and book their room reservations under your name (and reward account), but allowing them to pay for their room charge - unless, of course, you want to be overly generous.
