With Starwood’s new Every Night Counts promotion, members can earn double or triple points on every night for stays between Sept. 8 and Dec. 15, 2010. When you stay fewer than 10 nights during the promotion, you’ll earn double points on all of your nights and if you stay 10 or more nights, you’ll earn triple points on every night, starting with your first night. Hotels participating in the promotion include all nine SPG brands: Sheraton, Four Points, W, Aloft, The Luxury Collection, Le Meridien, Element, Westin and St. Regis. Visit http://www.spg.com/everynightcounts and register between Sept. 8 and Oct. 31, 2010.

Bottom line: For this latest promotion, Starwood is counting the number of nights and not stays, so one stay of 10 nights or two five-night stays, for example, will qualify you to earn triple points on all nights.
