Sonesta offers full service hotels and resorts in Atlanta, Boston, Hilton Head Island, Houston and Philadelphia, and through the Stay Sonesta promotion, members of Sonesta Travel Pass can get triple points on their next stay if they book by March 31, 2015 and stay by May 31, 2015. You must first register for the promotion by March 31, 2015 at http://www.insideflyer.com/link/?11903

Bottom line: You will only get the triple points for the first stay after you register, so register right before your longest stay planned. The points for each stay top out at 10,000 (including base and promotional points). A free night’s stay ranges from 1,750 to 2,500 points, so this is a good bonus.
