I think that is a bit harsh ... 2 months. I don't think so. Like anywhere in the world, one needs to aware of what is going on around them. The bigger question is getting work permits. You need to find a sponsor / contact person. Make sure this IS what you want to do. Living on an island and not changing living habits can be EXPENSIVE, electricty is expensive ... so a/c in a house can cost a bunch of bucks. Can't eat out all the time either ... might need to do some fishing etc. It is a different life style...which can be good or bad .. all depends on the person. We are all different. I know i could live there and love it. But i would need a/c every so often just to cool off during the really hot months.
Good luck on your adventure
