Hello Theresa and welcome to the Disney Parks Moms Panel.
Oh how I do enjoy using
MagicBands during my own much anticipated trips to Walt Disney World Resort!
MagicBands make for such great souvenirs too, in fact I have a whole chain of them linked-up together and hung in my kitchen and they make me smile each time I pass by.
From my own personal experience I've successfully
re-used MagicBands from trips of well over a year of more ago. However I had to wait until Resort Check-in or a quick visit to
Guest Relations to truly know if my
MagicBand was still active.
It may be helpful to know Guests can
manage their MagicBands via
My Disney Experience where it's possible to activate or deactivate
MagicBands, report a
MagicBand as lost, plus of course customise
MagicBands prior to arrival at Walt Disney World Resort.
Wishing you an extra pixie dusted upcoming visit to the magic of
Walt Disney World Resort.
Have a great Disney day.
~ Jane
