Very good experience
We enjoyed our 8 day cruise extremely. We must admit that we were lucky and saw many whale sharks at Darwin and many hammerheads at Wolf. It was our best dive trip so far (we both got 90 dives).
The cabins are well equiped but a bit run down (door did not close properly), a hole in the wall. Nevertheless we always had warm water, toilet was working fine and the bed was comfy.
Our guides did a superb job and we got special equipment (gps and radio) in case we got lost. So safety was never an issue.
The crew offered an awesome service. We got extra towels (sometimes warm) after each dive to quickly dry ourselves and a hot drink. What we did not like was the rental equipment which was so-so and there was no spare equipment, even though we told them months in advance. It‘s very pricey with 250 USD for a week (without dive computer), so we would have expected up to date equipment. One guide had to give his fins to a diver, because the only fins for rental were damaged.
The food was a lot, actually too much for us. It was a pitty that they tried to cook European style, which of course did not always work out. We always had something good to eat but would have enjoyed local food more.
