Hi there Erin! Welcome back to planDisney, and thanks for your question. The carefree ease of leaving my Disney Resort room in the morning with no purse, no wallet... just my most magical
MagicBand makes me so happy!
I love that you can re-use your MagicBands if desired, but sometimes a new design is just too tempting. I believe you're talking about purchasing a band from the Disney World website, that's offered with your reservation at a discounted pre-arrival price? I recently did as you describe, because I only wanted to purchase one new styled MagicBand, but not four for our entire party. I'm happy to report that yes, the site allows you to do this. You do not have to order a MagicBand for everyone in your travel party. Simply select the guest you'd like your new band assigned to, make your MagicBand choice, and proceed to checkout.
The designs they offer do change frequently, and you've got some time before your trip if you'd like to wait and check back occasionally on what they have available. But it sounds like maybe you've already got one you love... in which case, go for it! Or if you do opt to order one from the Disney Store, once you receive it just be sure to
link it to the appropriate guest in My Disney Experience.
I hope this helped answer your question, Erin. Sending pixie-dust for you to have a magical trip at Walt Disney World!
See ya' real soon!
Tami
