We are planning a 10 day vacation to Thailand/Cambodia. Our two options are July – Aug period or the December timeframe. The primary focus of the trip will be to do fieldwork on temples and architecture, but we would also like to do some vacationing in Phuket in the process. Any advice on travelling to Thailand and Cambodia would be appreciated.

I feel shamed to ask "Do you know Thailand ?" I am Thai. I found that Vietnamese and Indonesia language are available in Google translation machine but Thai. I think in South East Asia several countries such as Laos Cambodia Singapore Myanmar Vietnam Malaysia and China support studying Thai language. However, There are not much programs to promote study Thai or other applications for instance translation, dictionary, reading machine or OCR.
When I register the websites, they want me to inform the language but there is no Thai provided. What happened? Maybe my language is a minority of world language use.
