We leave for BKK in three days and was just wondering since I read on a blog that if you don't arrive in BKK with at least 10,000THB you could be turned away at the airport. Is this true? Is this the new law? We are a family of four. We were thinking of changing about $800usd into THB since we don't require much cash. All of our hotels and tours have already been prepaid. Should we just go ahead and get THB here in the US or are we able to wait till we get to BKK airport? Seems most on here were talking about using their debit card to withdraw at an exchange at BKK being the best option. TIA!
