Starwood has announced their Preferred Guest earning promotion for the first quarter of 2013. This time around the additional earnings will be based on number of nights stayed in a SPG property between January 15 – April 15, 2013. Here are the details, straight from the horse’s mouth:

With the SPG┬« Power Up promotion, you’ll earn 2,000 bonus Starpoints┬« for every four eligible nights you stay (up to 8,000 bonus Starpoints and 16 nights). Top it off with an additional 10,000 bonus Starpoints when you hit 20 eligible nights. And keep in mind: Nights will accrue across multiple stays. Looks like you’ve got real staying power.

Two very nice aspects of this promo are that the nights accrue across stays so you don’t need longer stays to benefit and it seems that all SPG-participating properties are in on the deal.

The promo will require registration at some point in January; we’ll be sure to post again when the time comes.
