Starwood has opened registration for their current promotion, Bring On The Nights. If you stay at Starwood hotels, you should go to the Starwood website and register.
Here are the details from the Starwood website:
Start packing so you can start earning. With the SPG® Bring On The Nights promotion, you’ll earn 2,500 bonus Starpoints® for every five eligible nights you stay from January 5 through April 30, 2014 — up to 10,000 bonus Starpoints and 20 eligible nights. Plus, get an additional 5,000 bonus Starpoints when you hit 25 eligible nights, for a total of 15,000 bonus Starpoints. Don’t miss out, registration ends February 28, 2014.
Earn on all eligible stays at any of the hotels and resorts in the SPG program. No exclusions. That’s more than 1,100 destinations worldwide across our nine distinctive brands: St. Regis®, The Luxury Collection®, W®, Le Mériden®, Westin®, Sheraton®, Aloft®, ElementSM and Four Points®.
Historically, Starwood’s promotions have been with “participating hotels” but it appears that every Starwood hotel participating the the SPG program will earn bonus points. I hope this is the new normal for Starwood.
