Plan to be in Thailand myself in September. Any suggestions?
Dont try to buy weed unless you enjoy Thailand prison.
Dont hire any Thai prostitutes unless you like AIDS.
BangKok sucks,get out of there as fast as you can.
BangKok Air Con sleeping train directly to ChiangMai is the think to do.ChiangMai is cool.Stay a few days,then head up to ChiangRai,a smaller more traditional town.
In between there are small places worth checking out,but its best to wait until you arrive,then ask the other travelers.
Theres a cool place called "Pai" (pronounced "Bye") thats a couple hours ride from ChiangMai.Its on a mountain and its a quite pleasent place to stay a couple of bong hits but dont buy any herion!!!
From ChiangRai you should head out in the morning on a 1 1?2 hour bus ride to Chiang Saen,on the Mekong River.Thats where I am now.Theres really nothing to do here,but you can just stroll around a couple of hours,visit the "Customs Museum" or the "Hall of Opium" (my friend's father is a Customs Officer there and just yesterday they caught a Chinese cargo boat with 2 Kilos of herion.Those guys are dead for sure,because China is always blaming other countries for transiting China with heroin,but really China produces lots of herion.
Every time I try to score weed in China they say,"Sorry,but Ive got some herion".
From Shiang Saen its another 1 hour bus ride to Chiang Kong,another Mekong town,then another 2 hours back to ChiangRai.
If you want to do any more than this in Thailand then you need more time and planning.
If you like this kind of travel its better to do it in China,but if you spend 1 week or 10 days in Thailand,go to the places I mentioned.
Even hanging in ChaingMai is enough,with a couple of day trips to the nearby mountain villages or Pai.
Remember,BangKok SUCKS and has NOTHING to offer,not even a proper "city center".
South Thailand is expensive.
Some people like to visit the islands on the West coast,near the Thai/Maylay border,but thats a bit involved and you will just get a sunburn.
