The atmosphere, instructors, dive sites, accommodation, social aspect just everything were all great. From day one we were welcomed into a lovely diving community. If it was for flights back home we would have stayed on to to our advanced course and done more diving... So leave yourself plenty of time to do MORE because you will, it also helps that Koh Tao is a lovely little island with 'gems' of beach side bars and restaurants. With the price of scuba diving over in Koh Tao, it is an opportunity not to be missed especially with Big Blue Diving!
