Ask yourself, what do you like to do at home? For us, we like to watch movies (So we download some and cross our fingers that there might be something showing on the ship that we’d like to see), I knit while listening to audio books (so we bring along several projects and books to listen to) we go to the gym (reluctantly but at least on the ship there’s an interesting view) we both write (poetry and short stories now but i’m thinking about a novel) talk on line to friends and family. So we do all of those things on the ship.
There are things we do on the ship that we would never do at home, like take dancing lessons.
What we don’t like to do is shop for food and cook for ourselves. So the ship is a perfect fit. We don’t go to the shows but I enjoyed listening to the singers around the ship and the various bars. Sometimes we even dance
