7. Social Skills
Onboard kids' clubs give your children the opportunity to hang out with peers from other states and even other countries, and making friends is pretty much a given. Kids as young as 3 pair off to babble about the splash park, while older kids bond over whether or not they were brave enough to tackle the racing slides. They could even end the trip with new BFFs to email and text when they get back home.
