Hi Leigh!
Thanks for stopping by the Disney Parks Moms Panel with your question.
My Disney Experience is a fantastic way to keep every element of your Walt Disney World vacation linked together and
MagicBands are the perfect way to access all of your plans. It is not essential that you all have MagicBands, although it is extremely convenient for everyone to have their own
Park Admission Ticket and
FastPass+ choices available at the touch of their wrist. MagicBands also allow each member of your party the ability to make charges to your Disney Resort Hotel (only if you wish), gives them access to the same Memory Maker account and so much more! Keep in mind that Disney Resort Hotel Guests are given complimentary MagicBands (which are also your room keys!) If you are not staying at a Disney Resort Hotel, you can purchase MagicBands
online or through the Shop Parks smartphone app. They can be reused which always makes me feel more comfortable purchasing them. I would highly recommend having one for each member of your party, if at all possible.
I'm hope you will come again if there is anything we can do to help you with your planning.
Have a wonderful day!
