For many years MSC Cruises has allowed children under age 2 to sail free on all sailings and for children ages 2-11 to sail free on select sailings.  Starting next summer, teens ages 12-17 will also sail free on select sailings in the low and mid-season!  On-board programming is available for all ages including baby care. MSC also features the LEGO Experience at Sea, including LEGO-designed playrooms, entertainment options, contests, games and character meet and greets. Other child-friendly activities and amenities include waterparks, 4D movie cinema, separate laundry for babies, DOREMI family activities, personalized prepaid debit card for children 7 to 17 years-old and more.  Four new ships are slated to launch between 2017 and 2019. The first, the 4,140-passenger MSC Seaside, will debut in December and sail out of Miami. The ship will showcase plenty of waterslides, water playground and more.
