I did have to show that, they will check it there at the counter, they circle/underline the dates of the airplane tickets and booking and the balance of your account. But I need to say that I cancelled my booking from the hotel before I arrived there so they don’t do a deep check it seems.
Uhmm Tod, where did you see this story? Because it would be really weird that a thai visa require a thai exit stamp ( what if the person has never been to Thailand) But I will have a thai exit stamp in my dutch passport from a few months ago. So I will be okay then?
