I’ve seen cruises for and by traditional Catholics. They feature activities of interest to Catholics, like daily Mass, conferences, single sex swimming, no immodest bathing suits, sleaze free night entertainment, etc. They are, unfortunately, super expensive. But I know of a couple who went on one for their 50th wedding anniversary.
Personally, Im not the cruise type. I also get motion sickness unless I’m outdoors, even in calm seas. I’d have to sleep on deck! It’s just as well because they’re out of my price range.
