Little girls’ dreams are about to come true this January when the Royal Caribbean cruise line starts setting sail with Barbie. Children ages 4-11 will be able to hit the high seas with the world’s most popular doll on a dream cruise complete with all sorts of Barbie-esque activities, such as a “tiaras and teacup” party in a decorated stateroom that is sure to be covered in the doll’s signature pink. Girls will get the chance to walk in a fashion show, take mermaid dance lessons, design their own doll outfit and more. And in case that wasn’t enough, guests will also receive gifts including dolls, blankets, toothbrushes and bags, so you can leave in true Barbie style. Booking starts this fall, with dates continuing through March 2013.
