The last time I went to Antartica I was the Navigation Officer on a Holland America cruise ship, and it some of the best, if not the most challenging sailing of my career to date. The cruises sailing from Rio to Valparaiso via the Falklands and Antartica and the fjords offer so much to see, from penguins and whales to magnificant glaciers. I recall the face of an iceberg shearing off as we passed, and thanking myself that I'd given it enough distance... But, I'd definately say there is an elevated level of risk involved when entering the Antartica on a ship, and whilst precautionary measures are introduced, you can never escape that risk fully.
