Did ya ever really want to? I certainly never have. I'd much rather pitch a tent 3/4th's the way up a mountain for a week and cook my own food on a campfire, than be locked on a floating barge with 4000 other people for a week.
I had thought about it. But like you, I suspected it would be more like my aircraft-carrier experience, than a vacation.
A carrier. Nut-to-butt, everywhere. Then, introduce copious quantities of liquor.
So, I put the thought on hold. A similar plan, maybe a substitute, was to book a cabin on a cargo ship, to Australia. Back in 2018 or so, it could be done - there were arrangers online. A few limitations, though - first of all, age. Had to be under 62 or so. Another was, you were forbidden from doing any work - Union rules. I could see that being taken by the ship's master, to keeping a passenger limited to his own cabin.
I put THAT on hold, too - thought I'd tour Central America, by motorcycle, first. I was gonna leave November of 2019 - and I got as far as staging my bike in Las Vegas. I was gonna fly down there, ride across the border, and enjoy the winter sunshine.
We saw how THAT worked out - that storm that wiped out half of Mexico kept me from being on the wrong side of an impenetrable border for the Coof Panic. Now, I no longer ride; I'm not interested in packaged tours; I don't trust ANYONE - swindles and random crime are epidemic everywhere in the West.
But, lest I have thoughts of maybe taking a cruise after all...this nooze blurb gets my head right.
