Both crew and the Instructor were both very professional and friendly. Excellent diving! I'll withdraw a few points due to a stomach issue which had to come from the food onboard. Having said that, I was the only one with issues so it could be just my stomach being oversensitive.
Visited dive sites: Similan Islands, Koh Bon, Koh Tachai, Richelieu Rock on a 4 Days / 3 Nights Liveaboard Trip in Thailand.
