Oscar i compared Bangkok with Honolulu at that site and then i saw Bangkok gets more rain. You get 3 metre of rain every year well that is a whole different story haha. If it is humid here then we sweat even without doing anything and only wearing a boxershort nothing else. It is too hot to do anything without airconditioning but i like it though because it is always better then Holland's climate.
Kao San road i know well, it is expanding a lot last years. It is a good place to meet people though i sure not call that area Thailand.
You can walk to the river from there and travel by express boat, they are very cheap and can bring you to nice markets. Also Chinatown is close from there and they sell much strange food there. There also is India town with loads of Indian vendors, an electronics market with mostly chinese or illegal electronics (Bang-Mo is the name). Or just walk around in chinatown and don't follow the crowd but go into the alleys and everywhere is something going on.
If you want to see plantshops then at wednesday it is at Chatuchak only for plants and not crowded. You can also go to the place i mentioned at the golden queen mango thread. If you want i can join you to there but the best way is a taxi with english speaking driver. Don't go there tomorrow because it will be traffic jam all day but maybe that is good actually to see the shops while in traffic jam.
I guess you have a smartphone with you because you can email all the time, i liked to walk from Kao san road to chinatown (by boat) and use my gps Garmin which worked perfect.
I just ate a NDM but it was not as sweet as in the summer. You should try one! Also try the green mango's with or without salt and sugar and spices.
