I checked my account and noticed I am getting nights towards my Platinum status from the card.  Does anyone know how those are figured?  I understand the points side, but I am not clear on how much needs to be spent to get a night.  I haven't been tracking it closely, so I am not sure when these new nights appeared, but its a fairly significant amount (13).  Thanks in advance for any help.
