As an update, we just finished our second trip to Dumaguete. Often, when you first go somewhere, it's so new and exciting you forgive some small stuff, but when you go back and the novelty is gone, you're not as impressed. That was not the case at Atlantis Dumaguete. We encountered the exact same superb level of service we did in February, and I believe that everyone in the group we brought was thoroughly pleased. I was delighted that people not only remembered us, but remembered our NAMES -- quite something when you consider we had only been there once before.
They have improved the coffee, although I'd still place it at hospital grade. A friend discovered that a double shot Americana made a MUCH better cup, and I wish I'd tried that earlier in the trip.
Nudibranchs are apparently seasonal, so we saw fewer on this trip, but in exchange, we saw a whole slew of flamboyant cuttlefish and a wonderpus, so I'd call it even. Visibility this trip was better in both sites (coastal and Apo). One of the sites we dove at Apo Island has to take the prize for the most diverse and beautiful corals I've seen anywhere.
Two nights, we got critter information lectures from Marco, which I found enormously interesting and most useful in helping me find and identify stuff, and also know what to try to show in my photographs. I wish they had those every night.
At any rate, we had another fantastic trip, and Atlantis will continue to get my strong recommendation as an excellent destination.
