@BrandonTL, for future reference, my buddy (and wife) was uninterested in a full Wolf/Darwin Galapagos LOB, plus she wanted to see everything else. So we did five days of land-based diving from San Cristobal, which was quite nice (dozens of hammerheads and a massive bait ball at Leon Dormido/Kicker Rock, very nice reef dives at Espanola, a good night dive, etc.), and then did an inter-island cruise which was outstanding. I think there's a good range of prices among the cruises, and the islands are really all that--snorkeling with penguins and marine iguanas, hiking up to see the tortoises, visiting a caldera. There are several operators on both San Cristobal and Santa Cruz, and we were able to shape our dive experience. The entire archipelago is other-worldly.
