Hello there, Tiffany! Welcome to planDisney. We love helping Guests get the answers to all their planning questions!
I wish I had a better answer for you, but unfortunately, I do not know of anywhere at Disneyland Resort that allows Guests to create a custom MagicBand+. If you were holding out on purchasing one until you get to the parks, I recommend heading to World of Disney in
Downtown Disney District for some of the largest selection on property. Once you purchase your
MagicBand+, link it to your
Disneyland app, and assign it to your ticket, you may have the option to customize the light-up theme, as well as vibrations and other interactive features. The really great thing about using a MagicBand+ at Disneyland Resort is that you can unlink it from one account and link it to another, or unassign and assign it to different tickets or Magic Key passes. I have all of our family's MagicBand+ devices linked to my account and mix up which one I use from visit to visit.
Be sure to take the time to find the interactive MagicBand+ installations throughout Disneyland Park that were added for the 70th Celebration. I had so much fun finding them all with my fellow panelists on a recent visit.
Tiffany, thanks so much for dropping by! I hope your upcoming visit is full of magic and plenty of Disney snacks!
Carrie
