Taking a page from Delta’s ‘elite rollover’ play, and making it doubly valuable, Starwood hotels is offering current Platinum members the ability to have their nights between October 1 and December 31 count both for 2009 (requalifying for status valid next year) and for 2010 (requalifying for status in 2011).  Registration begins September 9, and the FAQ is here.

Meanwhile, Starwood is offering double night credits from September 15 through December 15. This offer is open to Platinums (who have to choose between this offer and the ‘nights advance’ offer above), Golds, and select non-elite members who are close to Gold. Registration for this offer will begin on September 9 as well, and the FAQ is here.
