Vietnam is drawing more visitors from Britain for the winter sun season with 68 percent more Brits exchanging their pounds for Vietnamese Dong, according to a recent travel index.

Post Office Money results for the Fastest Growing Currency for Summer 2012 index revealed Vietnam, Brazil and Mexico are destination ‘hot spots’ with a spike in travellers ordering local currency for a holiday.

The boom in popularity of travellers seeking Vietnam to get a tan was fuelled by the introduction of direct flights last December and a host of new beach resorts opened in the area.

The 2014 World Cup and 2016 Olympic Games have drawn fresh attention to the South American host country Brazil with a 66 percent growth this summer.

Dropping from the top spot last year, Mexico managed to maintain momentum, placing at number three on the list.
