We stayed at le vimarn in november for 5 nights after some time in oz. The room was very nice and overlooked a small pound which was a popular gathering for the local frogs at night. Theres plenty of lizards about sunning it up, we also had a pet snake one day.The rooms were kept immaculate and the housekeeping staff were always friendly and very efficient. The breakfast buffet was excellent and managed perfectly by the manager and staff. The restuarants were also very good.
Le vimarn is a really nice resort and anyone visiting will enjoy it. But the resort and even the bay is more for couples and families. The other bays are easy to access by one of the 4x4 taxis, but you need to understand , by taxi i mean pickup trick with benchs on the back. Theres about 30 metres of road on the island and the rest is dirt track, taxi journeys can be quite exciting. But they are cheap and widely available. Le vimarn is Made successful by the staff, they all work very hard.

We have just returned from a 2 week stay in Le Vimarn Cottages and had a fantastic time. The drive from Bangkok took about 2 hours on motorway straight to the hotels own private pier where you catch a speedboat (about 20 mins) direct to the hotel.
The rooms are spacious well decorated and well equipped, you even get a pair of flip flops for the beach.
Some reviews have complained about breakfast, we had no such complaints, every day the food was great and the service even better, the staff in the restaurants are extremely attentive and go out of their way to ensure you have a great experience particular mention must be given to Payab the restaurant manager who is without doubt the best staff member I have met in any hotel I have stayed in and you can tell that his love for his job is filtered down to his staff.
My one gripe would be the prices at the hotel which I fear is driving customers away:
1) Food and drink prices whilst on a par with restaurants in England are high compared to other restaurants on the island which is a real shame as the staff are great and it would have been nice to spend more time with them. We found it cheaper to pay £4 each way for a taxi (an experience in itself especially when the clouds open) than to stay at the hotel each night, you have to walk through the O Restaurant to get to the taxis and most nights it was empty or only had 1 or 2 tables being used.
2 good options on the island we found are Buddies run by Englishman Paul and his wife in Samet village on the Saikaew beach and the Seabreeze restaurant on the lively Ao Pai beach which has a nightclub next door that gets going about 10.30 each night. A good meal can be had in both restaurants for about 150 baht compared to about 400 baht at the hotel.
At lunch we walked along the beach to the Lima Coco bar where drinks were about half the price of the hotel, the staff are lovely and soon get to know you, in fact after just 1 visit they knew our order, Daow and Tree deserve a particular mention for their great service.
2) I enquired at the hotel about a boat trip round the island for 4 people and was quoted an astonishing 7000 baht for a 3 hour trip, I later enquired at the Gecko bar (opposite Seabreeze Restaurant) and was quoted 400 baht per person! A staggering difference. We had our own private boat, were given water and melon and were able to go snorkelling.
3) The spa is overpriced a massage costs 1500 baht, if you walk to either Lima Coco or the Ao Prao resort you can get the same for 500 baht! 
That said, the prices are reflective of a 5 star hotel but you can get the same product cheaper if you hunt around.
We did eat in each of the 3 restaurants at the hotel and sister hotel and the food was great in each. Lima Coco was great for drinks but the food was not on a par with the rest of the island.
The great level of service continued right up to leaving the hotel, having paid our bill we waited for the speedboat and when it arrived we were touched to see that as many staff as were able made the effort to come and wave us off, including the hotel manager.
I was worried about staying for 2 weeks thinking it may be to long but the staff here were great and took care of us really well even when we had a problem it was sorted out quickly and efficiently.
I would definitely come back for another stay. Thank you once again Payab for your excellent service.
