We're going to Koh Samui for anniversary trip and we'll be staying at Sareeraya hotel (www.sareeraya.com), should be fantastic! It's on the quieter part of chaweng beach and they say it takes only 10 minutes to walk to the center. You might wanna check-it out! You're travelling before us, as we'll be there in February.. If you choose this hotel, do let me know your comments!
