Exchange money at licensed counters with clearly posted rates, which you will find in central areas and major tourist districts. Compare rates and fees before you change, since busy counters do not always offer the best deal. When withdrawing from an ATM, choose to withdraw in baht and decline any offer to convert the amount to your home currency at the machine, as the machine's rate is usually worse. Some banks charge a fixed fee per withdrawal abroad, so check your bank's fee schedule before you travel.
