Cruise ships aren't just transportation vessels, they can also be massive, floating amusement parks. Now, in a first for the industry, Gizmodo reports that Norwegian Cruise Line's next luxury ship will feature a two-level racetrack on its deck.

The Norwegian Joy, slated to launch from China next summer, will offer passengers more than just floating go-kart races. Other planned amenities include simulator rides, a hovercraft bumper car arena, and a 360-foot water slide. For cruisers more interested in leisure than non-stop stimulation, there will also be areas specifically designed to help them unwind. In a section called "The Haven," guests willing to pay a little extra will be granted access to a partially covered courtyard, upscale dining facilities, and a full-time butler.
