While Starwood’s fall promotion is valid for stays through December 20, today is the last day to register for the promotion. That means yesterday was the penultimate day to register for the promotion. And the day before that was Wednesday.
Through this promotion you earn double Starpoints on stays of one or two nights, triple Starpoints on stays of three or more nights. In addition to that you earn 250 Starpoints for stayed booked through spg.com, 500 Starpoints for stays booked through the SPG app (which is now also available for Android), and 250 Starpoints when you check in on Foursquare during your stay.
So if you haven’t yet, be sure to register now!
