Yes, children under the age of three are considered "guests of Mickey" and do not require a theme park ticket or a park reservation at Walt Disney World. This means your 1-year-old receives free admission to all four theme parks and both water parks. Furthermore, they can eat for free at any "all-you-care-to-enjoy" or buffet-style restaurant (like Chef Mickey’s) when sharing from an adult's plate. At table-service restaurants, they can also share for free or you can choose to purchase a specific meal from the children's menu. When making dining reservations in 2026, remember to include the child in your guest count so the restaurant provides a table with enough space, even though there is no charge for them. This age group also benefits from the Rider Switch program, allowing adults to take turns on height-restricted rides while someone stays with the toddler.
