Thailand is also one of the most visited countries in the world, and 99.9% of tourists never run into any problems. In fact, I’d argue it’s one of the safest countries in the world for tourists. Personally, I always advise people to choose Thailand if they are looking for travel to a place that ticks most boxes relevant for a vacation.
Just don’t insult the monarchy or sunbath in a temple while you are there. Neither should be that hard.
