THere are no barbed wire fences or machine gun nests at Hedo in Negril. At least there weren’t any as of 6 months ago.
Jamaica sports 2 Hedonism resorts, Hedo 2 and Hedo 3. We were on a cruise ship in Montego Bay, and took an excursion past Hedonism (Runaway Bay) - and you could clearly see the walls with rolls of Barb wire, and “observation” decks every 150 ft around the outer perimeter.
The Negril resort is on the tip of the island, so there may be security that isn’t as blatant, isolating that portion of the island. But, rest assured - there IS security.
