I like the idea of the boat going out only for one dive. We just came back from Anilao. The experience was great BUT after 5 days in Romblon and 8 days in Anilao, we had more and more trouble to stay warm for the second consecutive dives. The weather, this February, was not at his best: no rain but not much sun and quite windy. As a consequence the water température went down from 25 to 24°C and for 70/80 minutes dives, it was too cold for me with a 5 mm wetsuit.
