Marriott International is set to open 28 new luxury hotels across six brands in 2017.

The company’s acquisition of Starwood Hotels and Resorts in September saw the inclusion of St. Regis, The Luxury Collection and W Hotels brands to its portfolio, which includes The Ritz-Carlton, Bulgari Hotels and Resorts, Edition and JW Marriott.

Ritz-Carlton will be adding four new hotels in the next year, with openings due in Langkawi and Astana.

Luxury boutique brand Edition has recently opened its first Asian property on the Chinese island of Hainan and is set to open hotels in Bangkok and Barcelona by the end of 2017.

JW Marriott will debut two new properties, the JW Marriott Parq Vancouver and the JW Marriott Phu Quoc Emerald Bay Resort and Spa in Vietnam.

St. Regis unveiled the St. Regis Maldives Vommuli Resort in November, and will open five destinations in 2017 including Shanghai, Changsha and Cairo.

W Hotels opened its 50th hotel in Las Vegas last week, with the W Goa to follow on December 12 and six further openings slated for 2017 including Tel Aviv, Panama City and Shanghai.

The Luxury Collection has announced nine openings in 2017, including properties in Havana, Singapore and California’s Napa Valley.

Marriott Global Brand Officer Tina Edmundson said:

“Spanning the world from the most iconic hot spots to the ultimate undiscovered gems, the unmatched breadth and depth of our luxury portfolio uniquely positions us to cater to the increased demand of the rapidly-expanding cadre of affluent travelers.

“With luxury travel up nearly 50% over the past five years, we see a long runway for growth at the high-end and have a world-class, dedicated luxury structure in place to nurture and strengthen this coveted portfolio of eight diverse luxury brands.”
