Hi Jeffrey, and welcome to planDisney!
Congratulations on your upcoming
Walt Disney World Resort vacation! This marks the start of the planning phase, ensuring that you experience all that you can and have the option to tweak those plans, if needed, prior to your arrival.
You can certainly add a third theme park ticket for an additional guest. Begin by adding them to your
Family & Friends List. Once added, proceed to the
Parks & Tickets section, choose Theme Park Tickets, specify the number of days, and complete the purchase process. If the reservation is made under your account, you can conveniently share their theme park ticket with them using the
Disney MagicMobile Service.
If you would like to add them to your current resort reservation, you can modify the reservation to reflect the additional guest (as long as your room accommodates three guests). Sign in to your
My Disney Experience account and go to My Plans, where you’ll see a link to “Modify Reservation.” If your reservation cannot be updated or modified online, please
call and speak with a Cast Member.
We will be here to support you along the way; please let us know how we can help.
Have a magical time!
Raquel
