Here is one of many dozens of resorts in Muine, Vietnam, with amazing value. My room in this one was $15 a night. I had cable TV, Wifi, fridge, A/C, a great view and a gorgeous pool. Actually I took this picture from my balcony.
This was not a steal of a deal special bargain. This was the regular room rate. Ok, it was a single room. For a double I would have had to pay $18. But even if you had to spend a little more you could still live like a king on a small budget.
A dinner can be had for $3 (not including drinks), and a 4 hour jeep tour to various attractions costs $6. Sure, you can splurge and spend a lot more on fancier rooms and dinners, but you don’t have to.
