I got an email my magic bands are being shipped. I had 2 room reservations but I cancelled one.Two separate shipments are on their way. Do I return the extra bands to the front desk?
If it will make you feel good about yourself for being "environmentally correct", you can turn in the second set at the front desk and ask them to recycle them. They'll take them from you, smile, say thank you, then promptly throw them in the trash when you leave the desk. Magic Bands are not recyclable.
And as mentioned, all bands associated with your MDE account are completely interchangeable. You might as well keep them - particularly if they happen to be different colors.
