2. Keep in mind Disney’s age policy. When you hop from one theme park to another, you’ll need to remember Disney’s policy about minimum ages of unaccompanied minors in the parks. Clearly this only applies to your situation if you are planning to split up your traveling group across multiple parks. If you have older children who want to remain in a park while you hop to another, per Disney’s policy, those children need to be at least 14 years of age. If your children are younger than 14, you’ll need to ensure that an older child or an adult remains in the park with them. This is for the safety of everyone involved.
