TORONTO — A month after announcing a new long-term agreement between Marriott International and its resort division, Blue Diamond Resorts, Sunwing Travel Group is adding another property in Mexico to Marriott’s portfolio.

Mystique Holbox by Royalton, located in Mexico’s Yum Balam Nature Reserve and featuring 38 suites and two on-site restaurants, will be aligned with Marriott’s Tribute Portfolio brand later this year. The Tribute Portfolio is Marriott’s growing global family of independent hotels known for their unique design and vibrant social experiences.

Mystique Holbox will join 19 other Blue Diamond Resorts properties slated to be part of Marriott’s Autograph Collection, which comprises hand-selected hotels based on design and hospitality.

“We are thrilled to add Mystique Holbox by Royalton, the twentieth Blue Diamond Resorts property, to the Marriott portfolio,” said Laurent de Kousemaeker, Chief Development Officer of Marriott International, Caribbean and Latin America. “This exquisite boutique beachfront resort, which is located on the exotic island of Holbox, is a perfect fit for our Tribute Portfolio brand.”

As part of the monumental agreement with Marriott, Sunwing Travel Group will benefit from worldwide distribution in addition to the award-winning Marriott Bonvoy travel program with 147 million members worldwide.
