We are looking to book a cruise in the first two weeks of December and are torn between two itineraries. Both include Isabela and Fernandina, but one includes Espanola and the other includes Genovesa. Which island would be better to see in December? We are most interested in wildlife. I've read that Genovesa is the bird island, but then I also read that Espanola has the albatross and a large colony of blue footed boobies. Any opinions on which island we would get the most bang for a buck from? Thanks.
