Hi Cynthia!
I can completely relate to the conundrum of how to manage multiple park passes for children. When my daughter was little we put her park pass in a lanyard around her neck and it worked fine, but I was nervous the entire day that she would lose it or that it would fly off at an attraction. I suggest buying one of the Disney lanyards that has a zippered plastic pouch. That will make it less likely to fall out. You can buy one at
Disney Springs or any of the shops at the park.
You can also simply keep everyone's cards in your own wallet or zippered pouch in your bag. This will give you peace of mind and will also will help you as you get all the kids scanned in to the park. The
MagicBand certainly does make it easier to keep track of tickets, FastPasses and Photopasses.
Disney Moms Panel Tip: Take a picture of the back of all of your cards so if they get lost, you will have a way to track them.
Also, make sure to link your cards to
My Disney Experience prior to your trip.
Magically,
Stacy
