The thing about ED visas is that some people use them to get illegitimate long term stays. Immigration officers are aware of this so they may look twice at your passport. I am not saying its a bad idea just that it may be cause for longer conversations at the immigration. Also, from what I understand, if you are on an ED visa, you may have to take tests to prove you're studying and actually learning.
I lived in Bangkok for 4 years. I loved it. Eventually I got tired of not speaking the language so I moved to Pattaya where English is better understood.
I am also a quiet person so I found a quiet neighborhood in Pattaya. I am naturally a city dweller so the situation suites me because I can be in big city yuck when I want and I don't have to live in it.
