Hello Barry and welcome to the Disney Parks Moms Panel.
I have to admit I wasn't at all sure of an answer for your great question, so on your behalf I called and spoke with a very helpful Cast Member at
Walt Disney World Resort and Theme Park Information on 0800 16 90 743.
I'm very happy to share with you that
yes it is indeed possible to collect and utilize
MagicBands from your intended Walt Disney World Resort prior to checking-in - in your case, for the last 5 days of your holiday.
As I understood it from the Cast Member helping me, you will need to link your 14 day Disney Theme Park Tickets to your personalized
MagicBands via your
My Disney Experience account; doing this ensures the
MagicBands should be ready and awaiting collection at your Walt Disney World Resort hotel.
After arriving at your Walt Disney World Resort hotel speak with a Cast Member at Guest Services and explain you wish to collect and use your
MagicBands several days prior to check-in; the Cast Member should be able to assist you further from there...
You are also quite correct in mentioning that currently
MagicBands are not shipped to postal addresses outside of the United States of America.
If I can sprinkle any extra pixie dust on your upcoming holiday to Walt Disney World Resort please pop back to ask me another question.
Have a great Disney day.
- Jane
