The 16-acre luxury resort is being built on the site of the former Miramar Hotel and will consist of 161 one- and two-story guest accommodations, a main building, two restaurants, a bar, outdoor terrace, spa, two pools, a fitness center, beach club, 12,000 square feet for indoor and outdoor events and a 6,000-square-foot ballroom.
