We always holiday in Europe but next year we would like to go to further away for our family holiday. We have two teenagers and like to explore new places and relax by a pool. We can only go in the school holidays and need to avoid exam season so it will need to be end of July/beginning of August. I'm thinking Thailand(Bangkok then Koh Samui) and also like the sound of Malaysia or Vietnam. I'm worried about the rainy seasons. Where would you recommend?
