The world's 25 cheapest places to travel

Pretty much every traveller has experienced the mysterious disappearing bank balance. You do all of your budgeting sums, you save up the amount of money needed for your holiday, you head overseas, and then it just vanishes. Gone. Like it never existed in the first place. What did you even actually do? Travel is like that. You spend a lot more money than you think you will. You get caught up in the rush, in the excitement, in the "yolo" fever and you throw down far more cash than you'd budgeted for. You discover, too, that destinations are a lot more expensive than you thought they'd be. Food costs more. Accommodation costs more. The little expenses add up.
