As much as it's a pain living here, and the people are mostly horrible..
I hate to say it, but Thailand is a nice place for less than a month, especially if you've got that big a budget. All kinds of weird waterfall caves in the hillsides, oh-so-touristy temples, crocodile farms with elephant war re-enactments. You just haven't lived until you've experienced the smell of ten thousand crocodiles housed in tiny enclosures.
Nice place to visit, and the beggars aren't as horrible as the ones in India.
