Hi Carl,
Welcome to planDisney and thank you for sending us your question. It sounds like you are planning a wonderful trip to Walt Disney World Resort with your daughters, I am sure you are going to make some wonderful memories together!
Once you arrive at Walt Disney World Resort, you are able to visit any guest relations at one of the four Theme Parks as well as your Resort Concierge at your Walt Disney World Resort Hotel to add an extra day on to your existing Theme Park Ticket. Prior to purchasing your extra day, I would recommend verifying that there are still reservations available for you by using the
Theme Park Reservation Availability Calendar.
Please remember that guests are required to have both a valid Theme Park Ticket as well as a Theme Park Reservation each day you are visiting a Walt Disney World Resort Theme Park. Once you have purchased your Theme Park Tickets for both yourself and your daughters, please use the
Disney Park Pass system to secure your Theme Park Reservations and once reservations are confirmed, you will be able to view and modify your Theme Park Reservations under "My Plans" in
My Disney Experience along with all of your other reservation details.
I hope you have a magical time at Walt Disney World Resort with your daughters, Carl. Please let us know if you have any other questions, we are always happy to help.
