Hi Jaynee,
It's great to hear from you again, and I'm SO excited that your trip is so close! All of your planning is about to pay off with a visit FULL of magic and fun that will surely leave you and your loved ones with a lifetime of magical Disney memories!
In the famous words of Goofy, "Gawrsh!" That's sure interesting that you received a second set of identical
MagicBands! If you have a split stay at two different
Disney Resort hotels, I would expect that you'd receive two sets of MagicBands, but if you're just staying in one place, that's definitely unusual. Since no information is stored on your MagicBand and it's simply used to access your My Disney Experience account, either set of bands should be fine to use. If they were different colors, you could bring both sets and vary your MagicBand colors on different days of your trip based on your outfit or mood, but since they're identical, there's really no reason to bring both. I guess you just had a little extra pixie dust to receive an additional set of complimentary MagicBands!
They are reusable and their batteries are expected to last around two years, so you could always just hang on to your extra set for any other trips that you plan in the next couple of years.
Thanks so much for bringing me your question, Jaynee! It has been so fun to plan and dream along with you, and I hope that you have the most magical vacation!
Missy
