answer:Wow.. I just answered a similar question a minute ago! Mainly I was telling the OP that TESOL shouldn’t be taken via online correspondence. I really don’t know about Spain, but, yes, teaching English in Thailand the pay is modest, though you have the opportunities to travel around. My TESOL peers loved the experience, though the training was exhausting while it last. TESOL course in Thailand is known to be one of the most cost effective amongst other countries. If you don’t mind staying for a month, you could save quite a bit of $$. Good luck.
