I agree Chloe. Visitors have no reason to feel apprehensive about visiting this beautiful island.
It is enchanting, just like Axe said - the beauty, the people, and AC is not 3rd world rustic by any stretch of the imagination. Although you can book some of the older places which have that authentic caribbean feel to them, and some are just plain old, still I would say that by and large - not rustic. It is easy there. The hardest part is learning how to slow down and relax when you first get there. It is one of the most tranquil places I have ever been - but if you want action, it's there for you as well. Go and see for yourself.
