COSTA MUJERES, Mexico, June 29, 2026 /PRNewswire/ -- The St. Regis Costa Mujeres Resort, Cancún officially opened its doors with a ribbon-cutting ceremony that brought together industry leaders, government officials, project owners, and strategic partners, marking the arrival of a remarkable new luxury destination to Marriott International's portfolio in Mexico.

The celebration was attended by Josefina Rodríguez Zamora, Mexico's Secretary of Tourism, and Mara Lezama Espinosa, Governor of the State of Quintana Roo, who highlighted the importance of luxury tourism development in the region and its positive impact on the local economy, job creation, and the continued positioning of the Mexican Caribbean as one of the world's premier travel destinations.

The resort's owners also celebrated the opening as a significant milestone in their vision to establish Costa Mujeres as a world-class hospitality destination, underscoring the investment, dedication, and long-term commitment behind the project.

"This project represents the realization of a vision that began years ago with the belief that Costa Mujeres could become one of the world's most exclusive and sophisticated destinations," said Alfredo Bataller, CEO of AB Living Group. "Today marks an extraordinary milestone for AB Living Group, and we are immensely proud to share this moment with everyone whose passion and dedication helped transform this vision into reality."

During the ceremony, Idu Riberio, General Manager of The St. Regis Costa Mujeres Resort, Cancún, welcomed guests and reflected on the significance of the opening for both the brand and the destination.

"Today, we celebrate much more than the opening of a hotel—we celebrate the beginning of a new chapter for Costa Mujeres. This resort embodies the essence of St. Regis service, where elegance, attention to detail, and the anticipation of every guest's needs are at the heart of every experience. It is an honor to welcome our first guests to this extraordinary retreat overlooking the Caribbean," said Riberio.

One of the celebration's signature moments was the traditional St. Regis Sabrage, the brand's iconic ritual symbolizing the transition from day to evening. On this occasion, the ceremony carried special significance, marking not only the closing of the day but also the official opening of the resort and the beginning of a new era for Costa Mujeres.

The ceremony concluded with a guided tour of the property, where guests explored the resort's guestrooms and suites, distinctive culinary venues, and oceanfront spaces that define its contemporary luxury experience.
