Four years ago, one dollar would have purchased 40 Thai baht but recent currency conversion data has your dollar about 25% weaker with 30 baht being equal to one dollar. What is true in Thailand is also true in many of the other Asian countries.
Thai merchants are used to overcharging American and European tourists for years and while the Euro maintains its strength, your dollar is not but they will still charge you the same prices as they always have. This suggests your trip will be 33% more expensive than it should be.
Traveling on a budget is critical and there are several areas with which you can save money. The first issue is to only wash your clothes but then let the clothes dry in the sunlight. Thailand is extremely hot that your necessity for drying them is not critical. Washing one piece of clothing is 10 baht. With it being hot, the average person will have 3 pieces of clothing or $1 a day.
The next critical issue to save money on is food. If you purchase the food from local merchants with prices posted, you won’t get ripped off. If you go to a restaurant, they will give you the “tourist menu” with significantly higher prices.
Another area to save money on is housing. There is no need for the fancy housing, a cheap place that does not speak English will do just fine. All you need to let them know is date of departure, whether you want internet access, and how much per month. You should not pay more than 500 baht per day if you are really trying to cut back. If you get a fancy hotel, it can range from 2,000 baht to 10,000 baht.
Clothes and other products can be bargained. We recommend you driving out away from the Bangkok area to do your shopping. Since they are not used to tourists, they will give you deals.
