There is an extensive array of entertainment and activities on Navigator. (See Cruise Comapsses on the Navigator Profile Page). It seems like there is always something going on for passengers to interact with or to facilitate interaction between passengers. This is particularly true at night.
The five story Metropolis Theater is the scene for the ship's production shows and for visiting
performers. It is served by its own bar.
The full size ice rink is called Studio B. While the ice shows present virtuoso skating, they are more akin to production shows with music, costumes and theatrical lighting. Passengers are also allowed to skate on the ice at certain specified times. In addition, this area is used for concerts, parties and an adult scavenger-hunt called the Quest.
