Vietnam is definitely still one of the most affordable countries to travel in Asia. But, as with anything, your budget depends hugely on your travel style. Frugal backpackers should budget about 40 USD / 31 GBP a day, those in the mid-range are looking at 60 – 100 USD / 46-78 GBP per day and if you’re going luxury, then anything from 200 USD / 155 GBP up can be expected.
