Crystal Cruises is expanding its opportunities for family-friendly summer travel with new “Kids Sail Free” offers in Northern Europe and the Mediterranean. On four June and July voyages, junior cruisers age 17 and under can travel for free when sharing a third berth stateroom with two adults.

This is the first time ever the popular program has been offered in the Baltic, with three Crystal Serenity sailings of 10 days each on June 25, July 20 and 30, through Stockholm (overnight), Sweden; Tallinn, Estonia; St. Petersburg, Russia (two overnights); Helsinki, Finland; Berlin/Warnemünde, Germany; and Copenhagen, Denmark.

A seven-day sailing through the Mediterranean departs July 6 on Crystal Symphony, visiting Istanbul and Kuşadasi, Turkey; Mykonos, Greece; and Sicily/Taormina, Sorrento, and Rome/Civitavecchia, Italy.

“With attractive savings for bringing the kids along, combined with incredible opportunities to see and learn about Europe’s history firsthand, these cruises offer not only great value, but also invaluable experiences in terms of family bonding, world education, and memories” explains Jack Anderson, Crystal’s senior vice-president of sales and marketing.

Crystal Cruises’ dedicated onboard kids and teens spaces is a rarity among luxury cruise lines.  During summers and holidays, junior activities directors host complimentary supervised activities on board, ranging from behind-the scenes tours to cooking classes and scavenger hunts.

The Crystal Visions Enrichment Program also offers entertaining education, including Magic Castle at Sea shows and classes, iPad Digital Filmmaking classes in association with USC’s School of Cinematic Arts, and presentations from expert speakers.  Every cruise also has babysitting services, “finicky eater” foods, movies, library books, family-friendly excursions, and more available.
