Hello Dena, and welcome to planDisney!
Congratulations on your upcoming
Walt Disney World Resort visit! I know that you and the rest of your party of busy preparing for each magical moment.
I have had a similar experience, and I can tell you that you will be able to keep them under your
My Disney Experience account as long as the additional guests are added to your
Family & Friends List. You will need to be sure to
link the tickets to each individual in your family, and from there, you will be able to make your theme park reservations and plan for any dining experiences you desire. So when you purchase the first three tickets, link them to the guests in question, and when you buy the other three, link those to the remaining guests on your Family & Friends List.
Please return should you have additional questions; we are here to help.
Have a magical day!
Raquel
