Well this doesn't make any sense..
My status is valid until Feb 28 2016 (from the nights I accumulated during the year 2014).
So if I accumulated 50 nights/25 stays during Jan/Feb 2015, they're saying my status is still only valid until Feb 28, 2016??
In effect, what platinum concierge is saying is that I should accumulate more than 50 nights or 25 stays during 2015 to retain platinum status if the first 50 nights or 25 stays fall during the first 2 months of the calender year? Lovely....
