This was our third cruise with Arenui in the last 9 months. The boat was excellent on both earlier occasions and we found it still improved on this third trip, so we booked the fourth for next year. Rather than sitting back and enjoy their success, the owners of Arenui have taken guest suggestions to heart and made improvements where proposed, making the boat even better than it was before. One wonders how much better can it get???? There is absolutely no comparison with other liveaboards in the area, who all lag far behind Arenui in style and comfort. No other liveaboard has such beautifully designed and decorated huge cabins with real bathrooms not telephone boxes. No other liveaboard has such a huge comfortable lounge, sun deck and open air restaurant. There were 16 guests on board and we had 5 (FIVE) dive guides, all hugely experienced. We also made on-land trips and domestic flights before and after the cruise, which were organized by the Arenui office. All flawless!
