St Martin on the dutch side is fun! You can travel with the locals for 1-2$ anywhere. Meals are the excellent and the people are great. The french side is snobby. Lots of sailing coming in and out of the island and the fishing is good.

The best part of this place is that it is safe and you can go out at night and not have any problems(unlike jamaica, st. lucia, st. thomas(crack city), etc.
