Just returned from a wonderful 12 nights at the Merlin Hotel. It truly is a gem set in a jungle of fragrant flowers and with plenty of pools for all. The food was excellent and the staff extremely friendly and very helpful. I would recommend this hotel to anyone. Khao Lak is a very beautiful resort with spectacular beaches which were very quiet whilst we were there. There enough restaurants locally to the hotel to offer a choice of venue and all were extremely reasonable in price - average meal was less than £8 including a couple of cocktails/beers. Only thing that is expensive is wine.
Excellent excursion prices if booked locally at the Khao Lak Elephant Trekking travel agency at far end of town - did the Similan Islands - stunning; elephant trekking and kayaking - brilliant and James Bond and kayaking - great but very touristy.
Overall this was a brilliant holiday booked through Best at Travel using the hotels taxi for transfers. Would certainly go back again.
