In 18 years, I've been asked to produce an onward ticket once. Recently, I've been asked if I have one ever time, but not asked to produce it. I have loads of 30 day stamps where I stayed for three weeks or less, then returned home. I'd get a cheap onward flight (not a bus ticket) just to cover yourself, because I have seen people told to buy air tickets or no entry, unless they have a Visa.

Never mix laxatives and public busses....

It cost me 80 baht plus a lifetime of hopes and dreams.

@Joel ******

good advice, but can you tell us the timescales that you are thinking about? Days? weeks?

If it is well concealed in card, I would say - got one through, had one go missing....
