Hi Kerry,
I'm guessing you are from the UK since you booked through a UK travel agent. You will be able to customize your MagicBands once your stay at
Disney's Art of Animation Resort draws closer. However, MagicBands are not shipped to our international guests. Your MagicBands will be waiting for you when you arrive at your resort.
Once you have purchased your park tickets, you can link them to your
My Disney Experience account. Once you have linked your tickets, you will be able to make FastPass+ selections in advance of your trip.
Since you are staying at Disney's Art of Animation Resort, you will be able to make your FastPass+ selections 60 days before you check in.
Thanks for stopping by the Disney Parks Moms Panel. Be sure to let us know if you have any other questions!
Wishing you a magical holiday,
Amy H
