Hi there, Julie, and welcome to planDisney!
We appreciate you bringing your question to us and, as a tech geek, I love how Disney has embraced the wearable tech market with their MagicBands. Anything that adds magic and convenience to your Park visits is welcome in my book!
I'm glad that you've had prior experience with MagicBands at the Walt Disney World Resort. You are able to use Bands that you've purchased for Walt Disney World at the Disneyland Resort as long as they are
MagicBand+. I was thrilled when Disney announced that they would begin
supporting MagicBand+ back in 2022 and it's added a lot of convenience whenever I visit the Parks. However, older MagicBand types are not currently supported, so those will not work. Bands are only able to be linked to one account and one ticket at a time, and linking is performed through the
Disneyland Mobile App. I found that I had to unlink my Band from my Walt Disney World account before I was able to link it to my Disneyland Resort pass.
When will you be visiting the Happiest Place on Earth?
Fantasmic! just returned to the Rivers of America, and I can't wait to take my kids to see the updated nighttime spectacular! The show means a lot to many Guests and I was around when it debuted in 1992, so I'm glad to see it back again.
Julie, I hope that this was helpful for you. Please don't hesitate to bring more questions to us in the future if you think of anything else. You're always welcome at planDisney!
Wishing You a Great, Big, Beautiful Tomorrow!
