Thanks for posting this. Sounds like you had a good time.
I find Langkawi to be pretty yucky now as it has been developed so badly, like lots of Malaysia I guess. Pantai Cenang in particular is horrid now. Yoy can't even see the beach as it is almost completely blocked by shops and hotels. They also seem to have big problems managing garbage collection.
Such a shame as I loved it on my first visit about 9 years ago.
