Customer review from Liveaboard.com
“10/10 would go again. This was a fanstic trip to spend time with my brother and meet new friends. The diving was superb, never a dull dive day. The crew were always willing to help and were very friendly. The chefs and the food were amazing, no doubt I gained a few kilos on my vacation :). Even though some days the weather was not ideal, the crew and the dive guides did their best to still offer the best experience in and out of the water.”
Recommended for: The chef and the food were fantastic! Also very good on accommodating dietary preferences. the diving and the dive guides/penga captains were great! Always ready to help and provide the best service. the crew and other costa rican guests were very hospitable to us and made us feel welcome in their country..
