foursquare (via their blog) tell us about their latest brand partnership with Starwood Hotels & Resorts.
Starwood has made it possible for you to link your foursquare account to your Starwood Preferred Guest (SPG) account and then collect points and unlock rewards (free nights, airfare, etc) for check-ins that are tied to a reservation.
The mega-chain that includes Westin, Sheraton, Four Points and W hotels, among others, will also be offering specials and contests via foursquare check-ins.
This is the first partnership of this kind for foursquare and a hotel chain. According to their blog, this is the third time foursquare partners with a brand for a loyalty/rewards program.
Something tells me that this wont be the last time a brand ties their loyalty program in with a check-in app. This type of program is a great way to directly reward the consumers most inclined to be your brand loyalist.
