After arriving in Thailand and converting your C-note to about THB (Thai Baht) 3,400, you’ll find yourself burning through that amount fairly quickly if you stick close to beach areas like Phuket, less so if you go to northern or central locations like Chiang Mai.
Food in Thailand can be cheap, costing about THB 40-100 per meal.
Cheap accommodations are rife in many tourist areas, with private rooms going for about THB 300-400 a night. The abundance of budget hotels can lessen the quality of the travel experience, something that visitors to Phuket can confirm first-hand! Off the beaten path, you can snag some positively luxurious digs for a surprisingly low price — for example, the same THB 300 that gets you a small private room in Phuket can snag a riverside bungalow in Pai.
You can save further if you take the bus between Thailand stops, with fares ranging from THB 240 to 500 per trip depending on the distance traveled. Some routes might be closed depending on the weather; the monsoon season sometimes makes major highways impassable.
