Ali thanks for swinging by planDisney. Ordering those initial set always seems to be hard to get everyone to make a decision. I had a similar situation myself this past November and we left one of our discounted bands unused.
Getting the coolest themed
MagicBand+ is always one of my family's favorite parts of the planning leading up to the trip. The youngest wanted Star Wars related, my middle child wanted Stitch, and the oldest just wanted to make sure it wasn't too "kiddie." These all came together at one time but dear old Dad wanted something Marvel and the stars did not align so I ordered the kids so the specific designs didn't just up and disappear. They are usually discounted so we didn't want to miss out on the 4 versus waiting on the one. Unfortunately, once you order that initial set you forfeit any special offers on the other guests that didn't order one. Mine was not personalized because I decided to wait to get to
Disney's Hollywood Studios which has one of my favorite stores.
Celebrity 5 & 10 is my favorite place to search for cases, MagicBands, and MagicBand+.
While you are at Hollywood Studios make sure you visit
Star Wars: Galaxy's Edge. This place is so cool it looks like you are walking around on another planet entirely. Go see my friend Hondo Onaka and he will give you a job to earn some credits. It may include liberating some coaxium but you will be piloting the fastest hunk of junk in the galaxy.
Millenium Falcon: Smugglers Run is a way to gain some points with Hondo. Don't crash the Falcon though, he will take repairs out of your profit.
I hope this answer is helpful, and that you are able to find the MagicBands that you need for your stay.
Have a magical day,
Jeremy A.
