Hello Tracy and thanks for returning to the Disney Parks Moms Panel with yet another super question.
As the current UK Mum on the Disney Parks Moms Panel I certainly understand your question and I want to share with you that all Guests staying in Walt Disney World owned and run Resorts will receive complimentary
MagicBands, in addition to that overseas Guests like you and I receive our
MagicBands upon Resort check-in - so no need to even worry about postage!
Although, if your family is staying outside of Walt Disney Property you will certainly be able to purchase
MagicBands upon arrival at Walt Disney World Resort in select Merchandise Stores at Disney Resort Hotels, Theme Parks and in the Downtown Disney Area also within the Disney Stores located at Orlando International Airport.
Unfortunately at present it isn't possible to purchase
MagicBands here in our UK Disney Stores or online via the UK Disney Store.
I'm happy to tell you that all little Mouseketteers
under the age of 3 years old are considered the honoured Guests of Mickey Mouse himself and shouldn't need
MagicBands of their own.
Have a great Disney day.
~ Jane
