Starwood today launched their Double Take promotion, which, after registering, will give you the opportunity to earn double the points when staying at most Starwood properties, and 500 additional points if you book through their mobile app.
Typically, points are earned at a rate of 2 for every dollar spent, so this bonus brings it to 4 points per dollar. If you’re an elite member of their Starwood Preferred Guest, bonus points earned from that status are not doubled, however.
There are quite a few hotels that are not participating in this program, so book wisely. Otherwise, it’s a great opportunity earn double the points for spending 30 seconds filling out a form.
