While onboard a Norwegian cruise, you'll never run out of fun things to do. For those looking for an active vacation, being on a ship won't slow you down. Onboard you can swim, run and play. Most ships have basketball courts and features like rock climbing walls and miniature golf courses. For those looking for a more individual workout, the onboard gym is filled with new equipment, and check the schedule for fun fitness classes.

Passengers who have simply chosen to relax on their vacation will be pleased to know that each ship has a beautiful and calming spa that offers a space for you to relax and be pampered. Along those lines, many passengers spend time lying by the pool working on their tan or unwinding at one of the ship's many lounges.

While onboard, you should also be on the lookout for exciting demonstrations, lectures or classes. These include wine tastings, crafts and cooking demonstrations. You can also test yourself at trivia, or hit up the casino for a thrilling evening.

At night the ship becomes a hot bed of activity as the ship's staff put on exciting and fun game shows, and give you an opportunity to become a star at onboard karaoke. Norwegian hosts lots of performers too, including comedians, magicians and musicians. There are several venues onboard where you can catch their shows. Norwegian has also partnered with Cirque du Soleil, the innovative circus troupe presents awe-inspiring performances. There are also shows from the Blue Man Group and a selection of Broadway productions on some sailings. Later in the evening you can always loosen up at the disco or at one of the many themed parties.
