Hello and welcome to planDisney, Kevin!
Thank you for reaching out to us with a great question about
MagicBands! I am happy to hear that you will soon be returning to the magic of the Walt Disney World Resort!
MagicBands should work for about two years, but some of my friends have reported theirs working even longer! Cast Members at park entrance can check if your MagicBands still have some pixie dust left in them, and if they can no longer be used, you can stop by a will-call window to get physical tickets or purchase a new MagicBand.
Another great option that will allow you to enter the parks even if your MagicBands are not working is
Disney MagicMobile service. This service is currently available for iPhone, Apple Watch, and Google Pay enabled Android phone users and allows Guests to enter the theme parks and water parks by holding their mobile device near an access point. After linking valid admission to your Disney account, use the My Disney Experience app to create a MagicMobile pass, add it to your digital wallet, and head straight to the parks!
I hope this information is helpful, Kevin! Come back to visit us if you have additional questions and have a magical visit to the Walt Disney World Resort!
