As the photos show, Escape features one of the largest deck-top fun zones at sea with four major water slides; a restaurant-lined boardwalk; and a giant, two-deck spa with a flurries-filled Snow Room. Escape also will offer Norwegian's first dedicated nursery for young cruisers two and under; the first Margaritaville at sea; the largest ropes course at sea, a miniature golf course, a full-size basketball court and a bocce ball court -- another first for the line.

As with past Norwegian ships, Escape also will feature the line's signature "ship-within-a-ship" luxury suite area, The Haven, which has its own private pool, restaurant, butler service and concierge.

Escape is an expanded version of Norwegian's recently unveiled Norwegian Getaway and Norwegian Breakaway and the line's largest ship to date (scroll through the carousel below for a look at the Norwegian Getaway).

Soon-to-debut, 4,200-passenger vessel as it nears completion at a shipyard in Germany. The massive floating resort -- at 164,400 tons, 334,6 meters, the fifth largest cruise ship ever. As can be seen in the photos, parts of Escape still are a construction zone. But several major areas of the vessel are close to complete, and the ship is on schedule to debut in Miami in November 2015.
