We were on Marina in January doing the Antarctic and there were several specialists onboard to tell us about what we were going to see, some of the geology, the birds, and so forth. The naturalist in the group was on the bridge doing commentary when there were things to see. All four of the specialists were seen frequently on the decks and we asked plenty of questions of them. Was a great experience, even with overcast weather the whole time. The passengers on the cruise after ours, which went from Santiago to Buenos Aires had incredibly sunny days in Antartica. And we missed the Falklands due to high winds, they got to dock there and see things. Just luck of the draw on a lot of that.
