Thailand is a large and diverse country with something on offer for everyone.
What is good for some, might not be right for you.
Therefore, it is best to come to Thailand and make your own way, without listening to others.
You will have no idea what motivates them or if what they are telling you is the truth or not?
If you like the beaches, the mountains, the cities or the plains, research on your own the best place for you.
I find that tourists that have been to Thailand on a holiday, think they are experts in everything Thai.
There is a ton of false information spread on social media from tourists.
I would NOT trust information from someone I did not know personally.
If you need to depend on strangers to make it in Thailand, you honestly do not belong here.
Sort things out on your own and make your own way.
There is no substitute for doing your own research.
