I have been to Roatan this year in January, June, and November, and stayed at AKR each time. In January and June we only left AKR to go to the West End, and that was during the afternoon on our last day. In November we hired a taxi and drove around most of the island. As with any other island that I have been, the area right around the resorts are pretty nice, but you don't have to go very far to see areas that are not well kept. The taxi driver told us that some of the places we drove through are mainly occupied by drug users and miscreants.
I have seen areas of Bonaire, Grand Cayman, Cozumel, Dominican Republic, Puerto Aventuras, Cozumel, Costa Rica, Belize, Panama, and Puerto Rico that I don't want to be after dark. The same can be said for almost any city, even my small home town of Cape Girardeau MO. Common sense dictates that if you hang around in potential 'bad' areas that bad things might happen to you, especially if you don't live there. I have never felt unsafe at any of those islands but I stay close to my resort or hotel after dark. If you are traveling use the same common sense that you would use in your own home town.
