Koh Samet - Chang - Kood, resort recommendations pls

I stayed at the Seaflower resort/bungalows at lonely beach, second row of bungalows from the water front, very nice, generally quiet, peaceful, that was 800B, and on the waterfront 1200. I like the beach in front of Siam Hut, which is a beautiful little walk from Seaflower. Looking for other bungalow recommendation for Chang - Samet - Kood - Koh Mak. On Koh kood looking to try and go beginning of December if possible, want to avoid sand-flies. Thanks
