Platinum members of Starwood Preferred Guest who register at http://insideflyerus.wpengine.com/link/?2989 will earn an extra Starpoint per dollar spent on eligible stays through Dec. 31, 2010.

You’ll be earning four Starpoints per dollar on all your stays beyond the Platinum qualification of 25 stays or 50 nights this calendar year (and after you have registered for the promotion).

Also, the extra Starpoint per dollar will be earned on top of any other bonus offers including the current “Every Night Counts” promotion where you can earn double or triple Starpoints for stays through Dec. 15, 2010 (must have registered for the promotion by Oct. 31, 2010).
