If you really want to see a bit of 'real' Thailand, then you should visit Chiang Mai.
Chiang Mai is about half way between Bangkok and the Northernmost tip of Thailand.
It is a large city with crazy traffic!!
But..........
If you head north out of the city, the scenery is beautiful. Big mountains, elephants, rice fields etc..
I had a couple of brilliant days in Chiang Mai.
It was cloudy, and it did rain a lot.
I stayed in a hotel called the Pingporn Hotel. 700 baht for en-suite room. Very big. A bit old, but OK. Had 2 discos beneath it.
One was full of toourists and a couple of bar girls, the other was full of Thais having a night out.
If you can, hire 4 wheels instead of 2.
Chiang Mai isnt a Bar Girl town, although they do have them.
I used to get a girl to massage me at 2am in my room.
Great value
