Just wanted to add a comment or two about driving. It is a challenge and driving on the left takes some getting use to. But you will find it is much much easier to drive in Cha Am than in HH. Not nearly the traffic. It does take a bit of exploring or guidance to find your way around quickly. But once you know where things are you don't have to go to HH often unless it is for the night life. In that case I suggest a tuk tuk.
When you get here T.I.G.R. or I or both will be glad to show where to find things. You will find it much less costly than HH, not that HH is expensive.
