During the current official mourning period following the death of His Majesty the King, visitors are advised to dress "respectfully", but I'd hazard a guess and say that's not really being followed by some on and near the beaches.
The best exchange rate is the one you get when you take money from an ATM. Banks use the interbank transfer rate - which is the true exchange rate. Of course there may be fees from both banks associated with that withdrawal that makes it more expensive... but it's still the best method. almost 3 years ago
wear pants to any temple. all else, it is hot humid, be comfortable. not much difference i exchange rate. exchanged at airport and not much different in city. no need to run around looking for exchange place. many exchange office at airport inside/outside area. about 2 years ago
I know this is old, but for other people wanting the same information: only when going into a temple do you need to observe a dress code. Women need to cover their top - i.e. shoulders, and wear something longer than shorts. You can wrap a scarf around your waist to comply. Some temples provide the long scarves, or just buy one there. They are sold everywhere for cheap! It is usually hot and humid in Thailand, as a female, I wore shorts and tank tops or tee shirts the entire time I was there. Unless you go to a 'fancy' hotel or restaurant, you will not need dressy clothes.
You can change money at money changers who are everywhere, just ask around and compare rates - I am not referring to people on the street. I usually just get money out of the ATM in local currency as my home bank does not charge me. over 1 year ago
