Hi
I would recommend any one to go to Samui at least once in their life time however with the wrong agency people can be very very disappointed. I went with http://www.holidayinsamui.com/en/index.htm . The company helped me in many ways as there was a tour guide that took us to all the great places of the Samui islands and also helped in all the extra things that make a holiday stand out. I am planning to go summer 2010 again as it was such a great time. I have been to many countries around the world with several different companies but I really enjoyed myself with this company. The islands are so beautiful and scuba diving (personal favourite) are all included.
