I went to Langkawi with family in 2003 for Christmas and stopped over in KL for 2 days. We went to see the Twin Towers and Genting Highlands. The view of KL from the top of the mountain was great and I remembered my daughter enjoyed quite a lot with the facilities there. We stayed at Melia KL. Not far from the hotel there is a place full with Chinese restaurants and the sea food there was just delicious. The climate was pleasant when we were there, not as hot as in Thailand, but as for shopping purposes I still think Thailand is cheaper.
Its been fantastic & Unbelievable place. The people over there are very warm. Night life is very vibrant. Would like to go there again!!
