Langkawi is fantastic and definitely worth a visit.
I always like to check out other Starwood properties when traveling and had high expectations for the Andaman, given prior reviews and it's Luxury Collection status.
Again, some may prefer the jungle view of the Andaman (with older guests lounging in a standard pool), but I much preferred the million dollar sea views and infinity pool at the Westin. (but it was better than the Datai which I found plain and had a very murky pond water leading to the lobby)
Wish I had checked out the Four Seasons instead of Datai/Andaman.
