As the headline said,i´m goin´to Samui for a couple of nights in september,of course will i spend most of my time in Hua Hin

So...how about the weather in Koh Samui for that time? I think Samui would be a better choice then Phuket in September.
I also looking for a room,bungalow,i think i will go to Lamai,but i appriciate any recommendations...price:up to -1500Thb.
