In case anyone is interested, I did pack the wine in my checked bag and had no opportunity to transfer it to my hand luggage before getting onto the cruise ship. No one asked any questions and I no I didn't volunteer to any frazzled, rushed staff members: "HEY GUYS THERE'S WINE IN MY CHECKED BAG JUST IN CASE YA WANTED TO KNOW!" Bag was waiting for me when I got to my cabin, wine intact.
