Silvercar, a mobile-based car rental service, has partnered with Starwood Preferred Guest (SPG). As part of the hotel loyalty program’s “50 Night Benefit” package, SPG platinum preferred members can choose to receive a free Silvercar rental for up to five days.

The “50 Night Benefit” program allows SPG’s platinum preferred guests, who have stayed 50 nights in a calendar year, to choose from the following options:

- Free rental up to five days with Silvercar: unlock a silver Audi A4 using your smartphone
- Free Night Award: a night at any category 1-5 hotel or resort
- Five Elite Qualifying Nights: get an extra boost toward re-earning elite status
- 40% off a hotel bed, including the iconic Westin Heavenly Bed

“We love finding new, innovative benefits to reward our most loyal SPG members,” said Brad Olson, vice president of Starwood Preferred Guest. “That’s why we’re so excited to add even more choices to the 50 Night Benefit in 2016. From the ever-popular Suite Night Awards to new options like a free Silvercar rental, our members can travel in style whether on the road or in-stay at over 1,275 Starwood hotels and resorts. Now SPG members can open more doors with their phones: the door to an Audi A4 with Silvercar, then the door to their guest room with SPG Keyless.”
