Designed by the architectural firm Sordo Madaleno, the property utilizes glass and concrete to mirror the surrounding coastline, incorporating artisanal details that honor Maya history. The resort features 163 guestrooms and 50 suites, all offering private balconies with views of the Caribbean Sea. Interiors draw inspiration from local mythology, with stonework and lighting fixtures that pay tribute to the region’s sacred cenotes and celestial symbols.

Culinary offerings include nine distinct venues ranging from the all-day dining spot Costa Coral to the rooftop concept Shami, which fuses Japanese techniques with local ingredients. The resort also emphasizes wellness through its expansive spa, which utilizes traditional healing ingredients, and provides nearly 10,000 square feet of event space. This expansion represents a strategic push by Marriott International to solidify Costa Mujeres as a premier destination for luxury travelers seeking a mix of seclusion and high-end service.
