Marcie; There are other opportunities to see penquins and sea lions on the cruise besides Antarctica. There is a tour in the Faulklands that does it and there are tours from both Ushuaia and Punta Arenas that do. My experience with flightseeing and as a pilot is that you won't see too much from the air. It's just kind of a "I've been there" thing. The only exception to that is if it's a helo tour and you're in the left seat, next to the pilot. On the helo tour from Antigua to Montserrat I saw a lot from the cockpit, but Lynn didn't see much from the back. Not good for picture taking(movies) either.
