Occupying the eastern half of the island of Hispaniola, the Dominican Republic (or the DR, as it's often known) is a hugely popular destination, thanks to the portion of the country that most resembles the image of a Caribbean playland: the crystal-clear waters and sandy beaches lined with palm trees, of which the DR has plenty. This vision of leisurely days spent by the sea and romantic nights filled with merengue and dark rum is supported by what turns out to be the largest all-inclusive resort industry in the world.
