Starwood Hotels brands — and their guests — are now cashing in on location-based, mobile check-ins.
From now through July 31, Starwood Preferred Guest members with confirmed reservations can check in via foursquare from their mobile devices at more than 1,000 hotels in nearly 100 countries and receive 250 bonus Starpoints.
In a promotion running through May 31, each check-in qualifies guests for a chance to win a free resort night, which is hidden daily throughout some of the participating hotels. And through July 31, the check-ins will make rewards program members eligible to win a five-night resort stay with airfare.
