Plenty of UK travellers pass through Thailand for two or three days on the way to Australia or elsewhere in Asia, and a short stopover is exactly when you do not want money admin. Buy Thai baht before the trip from a commission-free provider such as Travel FX and the stopover stays effortless.
Airport transfers, a night market dinner, a temple entrance and a massage will likely all be cash. For 72 hours it is rarely worth hunting for fair card terms.
A modest amount covers a stopover comfortably, and any leftover notes can go towards the next visit, since Thailand has a way of pulling people back.
Travel FX is a UK online currency exchange with more than 18 years of trading and a 5-star Trustpilot rating.
