Have a Toy Story MagicBand from your vacation two months ago that you know your niece would love for her trip next week? Sorry, once a MagicBand has been assigned to someone, it can’t be reassigned. You can deactivate it if you’d like, but that’s about it. If you still want your niece to have that MagicBand all is not lost. Remove the puck, and replace it with a puck that is assigned to her. This should also work for MagicBand+.
