Yes, children under the age of 3 (specifically those aged 0 to 2 years old) receive complimentary admission to both Walt Disney World and Disneyland theme parks. These young guests do not require a park ticket or a park reservation. Additionally, they can eat for free at Disney's "all-you-care-to-enjoy" buffet and family-style restaurants if they share from an adult's plate. Once a child turns 3, they are required to have a "Child" category ticket (for ages 3–9). In 2026, Disney has introduced several special "Kids Free Dining" offers for children aged 3–9 who stay at Disney Resort hotels, but the baseline rule remains that those under 3 are always free of charge for entry. It is a good practice to have a digital copy of the child's birth certificate on your phone just in case there is a question about their age at the gate, though Disney typically operates on an honor system for toddlers. This "under 3" rule makes it one of the most cost-effective times to take a toddler to experience the magic of the parks.
