Hiya, Scott, and welcome to planDisney! I'm so happy that you're here with this great question about your upcoming Walt Disney World Resort vacation! It will be here in just a few short months, and now is a great time to make plans with your travel party.
Scott, you'll be happy to know that you should be able to purchase a ticket for one Guest without altering the tickets for the other Guests. The Guest who needs an additional ticket can use the
My Disney Experience Mobile App. They'll click the "+" button, then select "Buy Tickets and Passes." Then, all of the ticket options will be shown, and the Guest can purchase the ticket for the appropriate day. This shouldn't affect the other tickets.
When traveling with a large group, which is my favorite thing to do, I like to make sure we have an
Advance Dining Reservation each day. This gives your group a dedicated place and time to catch up and relax together. You might also consider planning a time to meet your group at a favorite landmark for a photo. Disney
PhotoPass Photographers are stationed throughout the parks to help you commemorate your group's time together. If one of you has
Memory Maker and you're connected in Family & Friends, that person can download the photos for you!
Scott, I hope this is helpful to you as you continue to plan your vacation. Please stop by planDisney with any other questions you have!
See ya real soon!
Jennifer
