Do this now: Starwood's fall promotion

Registration for Starwood Preferred Guest's Fall promotion is now open.  You'll earn double Starpoints on paid stays between September 1 and December 15, 2013, and 2,500 Starpoints for every 5 paid nights during the same period, up to 10,000 Starpoints after staying 20 paid nights (award nights and Cash & Point nights do not count). Unfortunately, once again there's a long list of non-participating properties.

Register now, before you forget.
