I agree with you that you'll need more than 2 weeks in Thailand. My old neighbor went and traveled around for 6 months, had the time of his life, found a girlfriend, went back to the US to take care of some finances then moved to Thailand to live there with his girlfriend for good.
New Zealand seems to be similar in my mind with all that beautiful scenery. I could easily spend months there.
I'd say Brazil or Japan for 2 weeks, Japan might be the best option for that short of time.
Those are my thoughts anyways
. Let us know what you pick!
