Great economic diving option for the Similan highlights

Economic option for fantastic diving around the Similan's with a safe and professional crew. Rustic boat but everything you need - good food, hot showers, soft drinks, chill out spaces and a good friendly vibe from a experienced boat crew and professional dive crew. Special mention to Audrey the dive cruise director for keeping everyone safe and happy, the rest of the Dive crew Rosie, Jean and Pablo for leading great dives (alongside Audrey of course), the captain and boat crew for getting us bang on top of cool dive sites and picking us up after, and of course the chef for some great food along the way. Beds were a bit hard but overall great value for money.
