I'm thinking of going on one of the adventurer trips to Thailand and / or Malaysia around July or August time. Is the weather there at this time of year a big problem? Is there anyone around who's done this in the summer who can tell me what it's like? I'm just a bit worried about sleeping in non air conditioned rooms at night if it's going to be stupidly hot. I'm sorry if it sounds like a daft question, but I've never really been abroad anywhere very hot so looking up the temperatures on the internet doesnt really help, I need someone to tell me what it's actually like.
Also I know it's rainy season in Thailand at that time of year but I'm hoping it wont disrupt things too much
