Hi, Eric!
Any valid Walt Disney World ticket can be linked to your
My Disney Experience account. If you do not currently have an account, you can open one up in a jiffy at www.DisneyWorld.com. Make sure each member of your travel party is listed. You can then link your tickets easily. Each member of your travel party will need to have valid park admission(s) before booking FastPass+ selections.
If you are staying at a Disney resort, your tickets will be linked to the
MagicBands that will be mailed to you about 3 weeks prior to your vacation. If you are staying off property and
buying MagicBands, you will need to link your bands to your account as well. All of this linking is easily done on your My Disney Experience account, but if you have any problems, call (407)939-7765 and someone will be happy to assist you.
Once you get all the leg work done, your tickets and FastPasses should work without a problem. However, I am always one for back-up, so keep your "hard tickets" with you in case there are any problems.
Have fun putting all the pieces of your vacation together. All the work will pay off when you enjoy your magical vacation in Walt Disney World!
Cathy
