Have dived all over the world and on many liveaboards but Arenui is the best. I feel worth the cost. Will be back. Boat: very well laid out and plenty of space. Outdoor space is outstanding. Diving: very well organized and impressed with the way the tenders were handled. Crew: very well run and the crew always helpful/attentive. A high level of service, which I expected but was very much delivered. Impressed with the level of experience of the crew and stability and continuity of the group. Food: food very good and well prepared. Overall excellent.
