Hi Gary!
Thanks for stopping by the Disney Parks Moms Panel. You are getting ready for a magical Walt Disney World Resort vacation with your little princess and I'm so happy to help you with your plans! Be sure to pick up a complimentary celebration button for your daughter to wear during your trip so Cast Members and Guests can celebrate with her!
When visiting Walt Disney World Resort, Guests who are 2 years old and under receive complimentary admission to the theme parks and water parks. So if your daughter will be 3 years old at the start of your trip, then you will need to
purchase a ticket for her. However, while Guests are on vacation at Walt Disney World Resort, they don't actually age for ticketing purposes. So if your daughter will turn 3 years old during your trip or after your trip completes, but is still 2 years old when your trip starts, she will be considered 2 years old for your entire trip and you won't need to purchase theme park tickets for her.
If she will be 2 years old for your trip, you won't need to worry about bringing identification for her to prove her age. Simply let the Cast Member at the theme park entrance know that your daughter is 2 years old and they will let her in to enjoy the magic!
Let us know if you have additional questions as you continue
planning your vacation with your little one. T-T-F-N, ta ta for now!
