Although to get to Phu Quoc, visitors must take connecting flights, resulting in higher airfares than most other destinations on the list, that should not be a reason to prevent visitors from coming to this paradise island, Travel+Leisure commented.

Rooms at one of the top-rated hotels in Phu Quoc start from $75, an American magazine revealed.

Travel+Leisure also shares that Duong Dong's night markets are filled with delicious and cheap eats, while sunbathing on white sand beaches and hiking through Phu Quoc National Park are free activities to enjoy.

Mérida, the capital of Mexico's Yucatan state, topped the list; followed by Bali, Indonesia; Negril in Jamaica; and Phu Quoc in Vietnam.

Beautiful scenery, reasonable prices and great photo opportunities are the top plus points in this year's review of affordable tropical destinations, Travel+Leisure reported.
