Not that responsive to your question, but of our 15 plus cruises, the 3 plus week trip on Holland to Antarctica was the best. The three days in the Antarctic were magical. We bundled up in every piece of clothes we own (face masks, scarfs, thermals) and stood on our balcony for hours. Wife, inspite of keeping her camera in her coat, still had to go in occasionally to warm the camera back up. Viewing great well into the night.

People not as brave, or in interior/window cabins were mostly on the lido, where viewing was poor as the windows "fogged" up. Some of the heartiest were out on the bow. Wife did some of that. We were 70+-.

We missed Ushia, as the "cold war" with Argentina was going on. Captain was concerned if we put in, we might not be allowed out. We were also going to the Falklands, disputed territory. We took our second trip above the Arctic Circle (this time proceeding along the Norway coast, up and back down to several ports in Iceland. We also did the Amazon on Regent Seven Seas. All of these put us in remote areas. I do not see it much different than the 8 flights to Australia.

When I was younger, I had to abandon an airplane (100 seats, 25 passengers) in Alaska, that started on fire as we went down the runway. Had we not been able to abort before getting airborne (we were just starting accent) things might have been different. Since we have "run" from cyclones in the South Pacific twice on cruises. One they locked us in the ship (chained the doors) with waves/water to the top of the ship for days. Our cruise from SAN down to Peru and back featured a volcano eruption, "title wave" , and earthquake on our way back, each was a day or two from when we left port! Nothing ate us on our recent trip to Africa with nearly a dozen safari drives/boats. I am going until I am physically to shot to do so. What I am trying to say, is there is risk in life.

So my response, the question is not the risk, but how important is the reward? Your preexisting condition (s)? and desire to make the trip, in the end are personal decisions.
