Years ago I would research, plan things our, book excursions, not so much anymore. We have traveled more non cruise than we have by cruise ship, although some places we have gone back to because we first were there on a ship.
We've been to five continents, and passed through Drake Passage, but did not make landfall on Antarctica, we were close enough. DH traveled Asia extensively for work, Korea, China, Japan, India, and Viet Nam in the Army. My only touch of Asia was the Asian side of Istanbul, but I never have had much interest in that part of the world. We were able to spend two weeks in New Zealand and eight weeks in Australia, with a week in Tasmania, that was somewhere I had always wanted to go since I was young. Our next B2B takes us to Iceland and Greenland, we have nothing booked yet and it is coming up soon.
Probably at least 20 years ago we went to a travel seminar with folks trying to sell all kinds of things. There was a lady attending that said as long as she was on a ship she didn't care where it was going.
At the time I thought it was a strange comment. I understand now, I think I'm about there.
