try to bring some food which u think is more convenient/ suitable for ur taste. I have went thailand few times before, still the food are toooooooo spicy for me/cant accepted by me. Almost every meal "relate" to tomyam, spicy...

Stay as near to train station as possible as the traffic condition can be very bad for your traveling if you move around by cab. Thai people are very nice and gentle, so never be misled by their dark and serious look.

its relatively safe if u stay out of places where demonstrations and riots are going on.... remember to go to chaktuchak!!
