Starwood recently announced their fall promotion, which means most business travelers who sign up will earn a bunch of extra Starpoints for things they’re doing anyway. Like most Starwood promotions, the details are pretty simple. From the Starwood web site:

Two is better than one. Register now to earn double Starpoints® on all eligible stays from September 1 through December 15, 2013 — with no limits. To top it off, you’ll get 2,500 bonus Starpoints for every five eligible nights you stay — up to 10,000 bonus Starpoints and 20 nights. And keep in mind: Nights will accrue across multiple stays.
