I enjoyed my dives and all the dive sites except one due to a strong current. The dive leader was great! Good food and accommodations were comfortable.
One complaint though. Clear instructions were given to guests to throw nothing overboard. However, I witnessed several times after meals staff throwing left over food overboard and dumping dirty dish water into the sea.
Visited dive sites: Similan Islands, Koh Bon, Koh Tachai on a 3 Days / 2 Nights Liveaboard Trip in Thailand.
