Hi Angela, and welcome to the Disney Parks Moms Panel!
As a fellow Passholder and a frequent Guest of Walt Disney World Resort hotels, I have quite a collection of MagicBands, including at least one in every solid color. It's fun, and I can match my MagicBand to whatever outfit I happen to be wearing!
Any MagicBands linked to your My Disney Experience account will work during your upcoming stay at the Walt Disney World Resort, including the ones you received as Annual Passholders and the brand new ones about to come your way thanks to your reservation at Disney's Coronado Springs Resort. Feel free to bring both sets along with you if you like. You can change your MagicBand to match your mood or your outfit!
If you don't want to amass a large collection like mine, you now have an option to refuse having new MagicBands issued to you after making a reservation for a Walt Disney World Resort hotel stay. You can do this from your My Disney Experience account, under "Manage MagicBands and cards."
I hope this helps you get the most from those MagicBands, Angela. Stop by again if you have any last-minute questions before your magical vacation begins. We love to help!
Keep Disney Dreaming,
Kathy K.
