Don't know if Trip Advisor's newsletter is the same for all countries, or indeed, if everyone has signed up to it. Today's newsletter reflected upon the 'top ten underrated destinations', "Great tropical destinations that aren't on everyone's radar - but they should be!"
Santo Domingo is 'number one'
La Romana is fourth. Destinations in Chile and Turks & Caicos Islands come in at two & three.
There's certainly more to this lovely country than you'll see inside an all inclusive!
