Hello! Advice please.... heading over from uk, would like to visit different countries in SE Asia but cannot pin down a set itinerary in advance and would like to be able to stay a little longer in places that I like or move on if I want to. Is it possible to buy a one way ticket into Thailand with a flight out of Thailand within 60 days and nothing further. I would then purchase return ticket or onward ticket as and when I decide? Any advice greatly appreciated. 👍😊
