The Riviera Palm Springs, a mid-century hotel located on 21 acres in downtown Palm Springs, California, will join Starwood Hotels’ Tribute Portfolio.

The resort will debut as the Riviera Palm Springs, a Tribute Portfolio Resort, in November 2015, after undergoing a multi-million dollar upgrade, including the addition of a new pool bar, wedding pavilion and enhanced lobby.

The Riviera Palm Springs includes an 11,000sq ft (1,022sq m) spa with 18 treatment rooms, as well as 398 guestrooms and more than 52,000sq ft (4,831sq m) of both indoor and outdoor meeting and event space.

The resort also offers a fitness centre, business centre and three outdoor pools. Circa 59, the resort’s signature Palm Springs restaurant, offers eco-friendly seafood, boutique farm meats and locally-grown produce from the Coachella Valley.

“The Riviera Palm Springs, with its memorable design elements and distinctive list of services and amenities, is a perfect addition to the Tribute Portfolio brand,” said Dave Marr, global brand leader, Tribute Portfolio.

“We look forward to working with the new owners and are excited to give our SPG members access to this magnificent resort in the classically chic destination of Palm Springs.”
