From October 1 through December 31, all qualifying nights at Starwood will qualify both towards 2009 status and 2010 status, much like Delta’s rollover miles program. Registration will open September 9. Check out the T&Cs and FAQs.
Furthermore, between September 15 and December 15 they have a double qualifying nights promotion towards 2009 status for Gold members as well as selected other members. Registration for that opens up on September 9 as well. Check out the T&Cs and FAQs for that too.
