I was in Koh Tao in the end of august and was traveling by myself. I was quite young and so I had no experiences before because it was my first backpacking-trip. I decided to go to the Big Blue Diving because of the recommendations of facebook and co. So I was there for around one week. It was not my plan but at least I also did my advanced-course because of the very good divingteacher (Phil) and the whole divingteam there. I always felt like a familymember of the divers, because they treated us like that. They were so friendly and lovely and very happy to have all of each divingstudents there. The divers (teachers) there are all very skilled in their job and that's why the dives were all very secure and cool! I always felt very good under the water and also at their own hotel there. The rooms are very comfortable and if you wish you can also have a better room for a bit more money. Koh Tao is also the cheapest place on earth where you can do your licences with divingmasters! Now I have my SSI Open Water and my Advanced licence and I'm very happy with it. Looking forward to visiting the team there very soon for a dive! People go over there, you can't miss that and you won't have regrets of it!
