Hi there all, usually there are many kinds of courses run over Songkran, some in the city, some in the country, some in language school, and some international schools run them. Does anyone know if they will resume this year? If so and you have recommendations, please post them. The only dates I can work with are April 13th - 17th.

Are you kidding? All public and private schools are closed during Songkran.

 

The course will start on 29 March and end on 4 May but it is closed on Songkran. Is this what you want?

There are many schools offering similar packages throughout the country. Many of them are using the term Songkran but the dates are much broader than Songkran itself, like the one you have linked. Unfortunately some of left Thailand some time ago and aren't up to date with the current state of affairs. I thought all schools were closed but am informed that language schools are open and running summer camps as they put it (throughout Songkran), how many are doing this I don't know.
