Q.I plan to travel to Bangkok , but I am not sure what is the best way to carry money. Travelers’ checks? And what about cash? 
A. Time was when the only way to travel was with travellers checks. We live in a plastic world today. Credit cards will get you anywhere. In fact, if you want to rent a car, you will need a credit card. Travellers checks will not do, no matter how much you want to deposit. In Thailand, as in most Southeast Asian countries, and China as well, you will find ATM machines anywhere from airports to the smallest village or hamlet. Most restaurants and shops will take credit cards. For cash, I always carry a few dollar bills. One never knows when you might need them.
