Marriott Bonvoy is making it easier to plan a fall getaway for less with a flash sale that has up to 20 percent off stays around the world.

The sale, which must be booked between Sept. 25 and Sept. 29, is available for stays from Sept. 30 through Nov. 11, Marriott shared with Travel + Leisure. Members of Marriott Bonvoy’s loyalty program will save 20 percent off weekend bookings, while non-members will receive 15 percent off their stays.

To take advantage, travelers must book a participating hotel through the online sale page. But with more than 6,000 participating properties around the world from the United States to the Caribbean, Europe, and beyond, there are plenty of options for a relaxing vacation.

“Fall is one of the most beautiful times of year, and our flash sale is the perfect way to take advantage of a last-minute weekend getaway,” Mandy Gill, the vice president of continent marketing at Marriott International, told T+L. “Whether you’re looking for an outdoor adventure or just want to take in the beauty of the season, we hope this offer encourages you to explore all of the unique experiences the Marriott Bonvoy portfolio has to offer.”

Spend a weekend tracing history or leaf peeping in New England with a stay in Boston at The Envoy Hotel, Autograph Collection, or head down to Texas to catch a football game or eat great Tex-Mex in Austin with a discounted stay at the Downright Austin, A Renaissance Hotel. Travelers hoping to plan a city escape on the West Coast can enjoy San Francisco’s unique charms while saving on a stay at the JW Marriott San Francisco Union Square.

As part of the sale, rates are non-changeable and non-refundable. Available days vary by hotel and location.

Marriott Bonvoy’s loyalty program is free to join and includes thousands of hotels across several brands from Westin and the W Hotels to the Ritz-Carlton and the St. Regis.
