This quaint beach town lining Caribbean’s coast is one of the most popular retirement places for American expats. One retiree from Florida described the place as so much like Key West 50 years ago. An article from the Huffington Post said people who live there by the beach could spend $1,500, and that means splurging for them–they eat out and go on shopping sprees often.
