At Walt Disney World, age limits are primarily focused on supervision and safety rather than a "maximum" age. To enter any of the theme parks or water parks, a guest under the age of 14 must be accompanied by another guest who is at least 14 years old. For boarding individual attractions, children under age 7 must be accompanied by a person age 14 or older. Regarding ticketing, Disney defines a "child" as being between ages 3 and 9; once a child turns 10, they are required to have an adult-priced ticket. Children under age 3 are admitted to the parks for free. In 2026, Disney also enforces strict "costume" rules: guests age 14 and older are generally prohibited from wearing full costumes or masks in the parks to ensure they are not confused with official "Cast Members," except during special events like Mickey’s Not-So-Scary Halloween Party. This grounded framework ensures a supportive and safe environment for families while maintaining the "magic" for guests of all ages.
