Hello, Lee!
Thanks for bringing your great MagicBand question to the Disney Parks Moms Panel. I really love how convenient it is to travel around the Walt Disney World Resort with nothing but a MagicBand on my wrist, and I'm sure you will be able to enjoy some of the many benefits of this colorful little device on your upcoming vacation.
Guests that choose to stay at a Disney Resort hotel receive complimentary MagicBands to enjoy a few hotel-specific entitlements, like unlocking the door to a Disney Resort hotel room or charging purchases to the room. All Guests, including those that choose to stay off-site, can benefit from using a MagicBand to enter theme parks and water parks (with valid admission), connect Disney PhotoPass images to a Disney account, and check in at FastPass+ attractions. If you choose to purchase a MagicBand, make sure to
link it to your Disney account with all of your other vacation reservations and purchases, like theme park tickets, Memory Maker, dining reservation information, and more.
I hope you have a magical Walt Disney World vacation, Lee!
