I am the opposite. I love to cruise, my wife and I have been on 23, many for long duration.
I like to write and getting coffee at 5am, taking a walk around the ship (outside weather permitting), and then a couple of hours working on a book project in the ship library is a great way to start the day and sets me up for exploring a new port later in the day or reading a good book and enjoying the ocean if it is a sea day. Then at night a fine dinner and a good show. A nice life, and it doesn’t have to be all idle time.
Another aspect I didn't enjoy was being a "guest", which means being treated like a retarded person. It's not the crew's fault, they have to do that because they get a lot of guests that sue when the guests do something stupid. But I don't really care for it.
