Stayed at Marazul for a month - mid September to mid October this year (70 dives). At times, you could hear the construction (hammer drill noise or workers voices), if you were outside on the inland side of units 6 to 15 or the units near the office. Some noise in the unit if the windows were open but I don't recall much noise while being on the ocean side. When I was there, they were working on 4 units in various stages of construction. If I recall correctly, the work does not start before 8 am and concludes by 4 pm. The new construction is called Punta Azul Ocean Resort. There is information on the web. Based on island time construction, I will assume that construction will still be occurring when I return in February 2024 for 2 weeks. I can update after I return. Feel free to PM me here.
