We went to the resort and stayed in the newer rooms close to the road. it's not ideal there because of the road, but in the rooms you hear no traffic at all. There is also a small pool infornt of the rooms, but you can hear the cars pretty well. Nevertheless, the rooms were big enough and clean with a nice balcony.
Beach villas are probably the nicest.
The beach is nice, but the chairs are like the ones in the public beaches and you can't really lie down. Same for the chairs at the main pool. I find this a very important aspect of my holidays, so I was not happy with the hotel for that reason only.
The Sabay Yen restaurant has good Thai food and evening seafood bbq.

I would give the Coconut Beach Resort a 5 star rating. I suppose it depends on what you are looking for in a holiday, but it was perfect for my needs. My daughter had been before and she asked me if I would go with her this time. We were both tired, she with a lot of study and I had been very busy at work and with homelife.
We stayed in a Superior Bungalow, right on the beach, between September 26 and October 2 2011. It was the 'Green Season'. Not a lot of holiday makers about so we had the beach to ourselves most days. The restaurant next to our Bungalow was lovely, good food and pleasant staff. No, they couldn't speak very good english, but we were in Thailand after all. Their smiles and keen service more than made up for the lack of understanding. Every day our bungalow was cleaned, clean sheets, surfaces dusted and the bath towels were made into the most delightful animals. An elephant one day and some sort of sea creature the next. All the staff were very helpful and helped make our holiday the experience of a lifetime.
We wanted peace and quiet and that's exactly what we got. Choose between the beach or the little pool or go wandering up the beach and find more delightful restaurants. The breakfast, which was included in the bungalow price was fantastic. A buffet of fresh fruit and vegetables, or there was hot food if you preferred. The Chef will make you whatever type of eggs you want. My favourite was always the omelette. Yum.
Thankyou Coconut Beach Resort for the wonderful holiday and experience. I'll be back.

Some of the rooms is located next to the road, make sure you do not get one of them. The beach is good but there are not enough chairs for everyone who wants one.
