Don't forget your mosquito repelant!
If you do get bitten, get the best stuff ive tried. Topical cream for Jelly Fish. I know,I know, but trust me, nothing i've ever tried before works!
Remember to have the Thai soup,Tam Yam Gung, and one more thing, bargain hard in the markets at least 1/2 what they tell you!!!
