I doubt if those like the boat house isla bonita, etc are include as far as I know they are grandfathered in. The beach came to them, when they were built they were more than 60m from the water. I doubt if parts of the hamaca is 60m from the water
Hamaca methodically caused the erosion at the right hand side of the beach with the construction of that jetty/wall to keep the rest off their public beach. My first and only visit to a resort was in Hamaca, took me a week to get rid of the stomach issue.
