Think of these family-friendly, all-ages ships as amusement parks at sea, and you won't be too far off base. They have everything from game rooms to large gyms — and even bowling alleys. Best known for having pioneered "Freestyle Cruising" over a decade ago, this family- and budget-friendly line of mega ships was at the forefront of moving the cruise industry away from the dated traditions of the past.
Now, many mainstream lines have followed suit and offer open seating in their dining rooms as opposed to the more formal early and late options with assigned tables and tablemates. Norwegian also relaxed the evening dress codes, and you're much more likely to see casual attire in the dining rooms at night.
The result? These ships are loud and boisterous, with plenty to do all day and all night long as well as open casinos and music that echoes from one space into another.
