Yes, babies and toddlers under the age of three can enter all Walt Disney World theme parks for free. Specifically, if a child has not yet reached their third birthday, they do not require a park ticket or a park reservation. This "free" status also extends to dining: children under three can eat for free from an adult’s plate at "all-you-care-to-eat" buffet locations like Chef Mickey’s or Crystal Palace. If you order a separate meal for them at a standard table-service restaurant, you will be charged, but sharing is always permitted at no cost. In 2026, Disney has even introduced a special offer where children aged 3 to 9 receive a free Disney Dining Plan with certain vacation packages, but the "under three" rule remains the only way to get completely free admission. When booking reservations, you should still include the baby in the total guest count for fire code and seating capacity reasons, even though their "ticket" cost will be zeroed out in the final checkout.
