What do you like to do on the ship besides eat and watch ocean waves? Do you mostly relax, stay busy, or alternate busy periods with relaxation? Does it depend on the trip itinerary and duration or the ship you are on? I want to know what a perfect sea day for you is and what you would do when the ship is in port if you didn't want to get off it.
My first cruise will just be an introduction to cruising, but after that one, starting with the Sapphire Princess next year, I will only start to relax on a sea day after my late supper because I want to hear lectures, take classes, watch demonstrations, swim, hear music, and watch stage productions. For me relaxation will mean sitting on my balcony watching water, in a hot tub, or at the library with a book. I would only stay on the ship when it is in port if it's boring - for example, Ensanada on a Hawaiian cruise.
