I have been reading with great interest all the recent posts. Thanks for the great tips you have all been sharing. We are coming for the first time to Thailand as a family of 4 (2 older teenagers) on the 19th December. Can't wait. However I would like to ask about clothes. I know it is humid- and warm so shorts/t shirt in the day. What about at night? are shorts accepted or should it be trousers, also will we need long sleeved tops? wondered if there is a breeze in the evenings. We have booked the lake/safari 2 night trip and will book an island day trip. I know that people do recommend long sleeves at night due to mosquitoes.
