Disney Cruise Line serves families with kids like only this company can. The prices are high, but for lovers of Mickey Mouse, these cruises are worth the splurge. In addition to all of the characters and brand partnerships you would expect on the at-sea version of this venerable brand — from princess meet and greets with Elsa and Anna to "Star Wars"-themed parties on deck — you’ll find polished, well-executed service at unprecedented levels for a family-focused cruise line.
