I went on one cruise, to Alaska the summer before Covid. It was pretty obvious as a petri dish for disease, and although we enjoyed our trip, vowed I would never go on another.
Oh, I just repeated what was in the article — I wondered about that, too.
Agree about cruises, although it does sound the best way to see Alaska.
I went on a Caribbean cruise (with husband) back in the 1980s. I had a super high stress job and the two people who had sat in my chair before me each ended up in the hospital within a year. I was headed there, weighed less than 90 lbs at 5’6 (female, 20s). One of my TV network reps could see I was about to end up like my predecessors and gave me the free cruise. (What a dear, and I will always be grateful.)
I gained 11 pounds in one week! It saved my health (and we really enjoyed the snorkelling at St. John’s), but I agree about a Petri dish. Never went on another and would not want to, either, unless I needed to rest and fatten up for free again and it was a quiet old folks type cruise line.
