Im hope to be taking 150,000/200,000bt with me for a month, But I plan to party hard while im there, I spent 100,000bt in 10nights there and that was not including flights or accom in low season
But this time ill be watching the cash, If I was you I would not be able to stay in los on that amount of money, Unless you plan to chill nearly all the time and maybe go out to a bar once a week, Eat at the cheap places where the thais do, Use public transportation as a means of getting around, Then maybe you can get 6months out of your money, But it will be a bit of a struggle but could all so be a good experience.
