Norwegian Cruise Line is offering a 50% fare discount for children on European cruises.
The line has two ships based in Europe year round, Norwegian Jade and Norwegian Spirit, and a third ship will offer spring and summer cruises in 2013.
To qualify, children must sail with two adults in their cabin. The offer applies to passengers age 17 and under.
A few other cruise lines offer special fares for kids, including MSC Cruises, where children under 11 sail free and fares are discounted for passengers ages 12 to 17.Follow Tom Stieghorst on Twitter @tstravelweekly.
