Greetings, Ella!
While we don't know exactly what Cinderella was dreaming of when she sang,
"a dream is a wish your heart makes," it's possible she dreamed of unlimited
MagicBands so that she could match every Disney bounding outfit.
Ella, as a guest who always packs multiple MagicBands in my luggage, I appreciate this question. The quick answer to your question is YES, you're welcome to use previous MagicBands. To check all the active MagicBands associated with your My Disney Experience account, simply log in and hover over the bold "My Disney Experience" until you see "My MagicBands and Cards." From here, scroll down until you see an arrow by your character and click on the arrow to expand. You'll then see all of the active MagicBands associated with your account. Any of which can be used to open your
Disney Resorts Collection hotel room or gain theme park access.
Ella, I hope this helps as YOU are dreaming about April and
the walk toward Cinderella Castle. If you have any additional questions, don't hesitate to come on back to planDisney. We are always eager to test out our Fairy Godmother skills and help guest's create Magic.
Lauren
