A lot of books get read during a voyage like this one. I am currently reading Sherman Alexie's Reservation Blues, and Tom Clancy's Politika simultaneously. I never like to read just one book at a time. Another place you can generally find solitude is in the ship's workout room. I was surprised to find Lifecycles, a rowing machine, weight benches and a variety of other exercise equipment in a small room deep inside the hull of the ship.
Most people find time to work out two or three times a week.
The ship also has a small library. There is a year's worth of paperback novels waiting for anyone who forgot to bring reading material. With something like 50 computers on board, you can believe that there is a wide variety of computer games for those addicted to such pursuits. There are also shared forms of recreation aboard. One of the most popular is the movies.
