Hi Namphon, Welcome, I've recently joined the site myself, as you say the information and advice given is very useful everyone seems very open in helping out. If the ex-pat community in HH is as warm as they are on this site then I think I should move out soon !
You're lucky to be escaping this weather so soon, I have 5 more weeks of it before my HH visit.
Best of luck on the site and enjoy your trip.
RIG.
