Carnival Cruise Lines ought to be planting some big-ass Valentine’s Day smoocheroos on the 4,200 smelly suckers who thought they were taking the Love Boat to Cozumel but found themselves aboard a barely floating honey wagon being towed to Alabama.

Alas, the waters in which these buccaneers ply their trade are full of pinstriped sharks, heavy on teeth but lacking in the lip department.

Lawyers speaking with The New York Times say the ability of passengers to sue cruise-ship operators “is sharply limited,” and the location for any court action generally fixed in some shithole (Miami) favorable to piracy. “Shiver me timbers, matey, ye must file yeer complaint on Skull Island, arr.” Plus passengers are barred from collecting for emotional distress unless they are actually flogged, keelhauled or forced at cutlass point to walk the plank.

No gambling? No drinking? No showers? Sounds like a little trip to heaven.

Herself is on a little trip to Vegas, where they have all three of the aforementioned items plus “Love,” the Cirque du Soleil tribute to making money. I would insist on a functional toilet afterward, or perhaps during. But it was a girls’ outing and I wasn’t invited for some reason, so I’ll just have to make do with my memories of the Fab Four’s debut on “The Ed Sullivan Show.” Was it really almost a half-century ago?
