Starwood has announced their Fall 2015 promotion called Stay For More. The promo is pretty straightforward. Earn 2x Starpoints on stays of 2 or more nights plus an extra 300 Starpoints on stays of 3 or more nights. The promo runs from October 1, 2015 through December 20, 2015, and you must register by December 6, 2015 in order to participate.

Here are the Ts & Cs:
Registration: SPG® Members must register online at spg.com/stayformore by 11:59 p.m. Eastern Time (ET) on December 6, 2015. Registered members can earn bonus Starpoints® for each eligible stay of two or more nights between October 1, 2015, and December 20, 2015, (the “Promotion Period”) at participating Starwood hotels and resorts. A list of nonparticipating hotels and resorts can be found at spg.com/stayformore and is subject to change.
Earning: Registered SPG Members will earn double Starpoints on eligible stays of two or more nights, and double Starpoints plus 500 bonus Starpoints on eligible stays of three or more nights between October 1, 2015, and December 20, 2015. To view the complete list of hotels and resorts that are not participating in the promotion, visit spg.com/stayformore. Members who earn double Starpoints will earn an additional two (2) Starpoints per eligible US$1 spent (for a total of four  Starpoints per dollar spent). Elite-level extra Starpoints earnings and other bonuses will not be doubled. Only the base two-Starpoints-per-dollar earnings are doubled. There is no limit on the number of bonus Starpoints that can be earned during the promotion period. Offer is eligible with other Starpoints promotions; however, each offer will award bonus Starpoints independently of each other, and offers are not combinable.
Bonusing: Double and bonus Starpoints will post to the registered Member’s account within 2–4 weeks after the qualifying stay posts.
Eligible Stays: An eligible stay is defined as two or more consecutive nights paying an eligible rate in the same hotel, regardless of the number of check-ins or checkouts that occur, and posting to the member’s Starwood Preferred Guest® account. An eligible rate is any rate that is eligible to earn Starpoints in the Starwood Preferred Guest program. A listing of SPG-participating hotels and resorts and a description of eligible stays and eligible rates can be found at spg.com under the program terms and conditions. See Section 2.1 for the complete definition of eligible rates. Note that certain prepaid room reservations, such as when the booking is made through a third party — including but not limited to travelocity.com, expedia.com, orbitz.com and delta.com — are not considered eligible rates and do not earn Starpoints or qualify for promotional earnings. Stays must be booked through any Starpoints-eligible channel which includes a travel professional who books through those channels or the GDS.
There is a fairly significant list of hotels that are not participating in this promotion. Here are more FAQs regarding the promo.
As promotions go, this is similar to what other chains are running for Fall 2015. It’s nothing earth shattering, but if you think you might be making any Starwood stays between now and the end of the year, be sure to sign up so you get as many Starwood points as possible.
