Yes, but you must be at least 14 years old to enter a Walt Disney World or Disneyland theme park without an adult. Disney's 2026 policy states that children under the age of 14 must be accompanied by a guest who is at least 14 years or older. This means a 15-year-old can technically supervise their younger siblings. For boarding attractions, the rules are slightly stricter: children under age 7 must be accompanied by a person age 14 or older. While teenagers can roam the parks independently once they meet the age requirement, they still need to be aware of the "Code of Conduct" regarding behavior and attire. In 2026, Disney security may occasionally ask for proof of age if a guest appears to be under the threshold. It is also worth noting that minors cannot check into Disney Resort hotels; you generally must be 18 or 21 to hold a room reservation, depending on the specific resort and state laws.
