I can not imagine being denied entry into Thai.
110 times over 25 years. Stays mostly 3-4 days, others one month (when it was the rule for visa exemption).
Touristing all over Thailand, hotels, interesting places my Thai wife picked.
Look at this. Khon Kaen, trying to find our hotel, we (me, as the driver) of a rentacar, got into one way street, opposite direction.
Policeman stopped me. Called his commander (they were hunting no helmet motorbike riders, they were 20 of them) and what happened?
The Thai police commander spoke to my Thai daughter (then 17), "Noong, passa Thai) she told him we were lost.
The police commander ordered his policeman, on BMW white high power bike, to lead us to our hotel.
No fine.
Khon Kaen.That is why I have always Isaan.
