Your sense of adventure is underwhelming. Cruise lines are anxious to protect their reputation and are liable to civil suits. In my admittedly limited experience, they’re ok, I suppose it depends are where you go and what you do.
Always buy trip insurance and pack lots of clean undies.. and socks. We cruised a pile of times over the last 30 years..
a 10-day Alaska cruise in and out of San Fran in late May is up next..
I never sailed on Carnival, mostly RCCL and Princess, just the luck of the draw, wifey is the big # cruiser , we have never been norovirused or too badly rocked and rolled.. It’s a great way to see things and not have to worry about driving a lot or having to cook.
