Cayo Coco, Cuba

This island paradise is a tourist's dream, but the reality for residents is far less glamorous. With a surface area of 370 km2, Cayo Coco boasts over 5,000 hotel rooms catering to the 32,000 tourists the Jardines del Rey project plans to eventually accommodate. However, the construction of the 27-kilometer causeway linking the island to the mainland has caused environmental concerns, disturbing the tidal flow and altering the water's salinity and temperature. And while the island's natural beauty and wildlife remain a draw, the bureaucracy involved in daily life is a persistent headache. Cayo Coco is best suited for those seeking an all-inclusive resort experience, not a permanent relocation.
