Hi Rebecca!
Thanks for coming by to see us at the Disney Parks Moms Panel. As you experienced on your last trip,
MagicBands are a wonderful addition to a Walt Disney World Resort vacation because it's just so convenient to have access to your theme park tickets, FastPass+ reservations and Memory Maker account with just the touch of your MagicBand. MagicBands do have a small battery that does have a limited battery life. However, in my experience I have successfully used my MagicBands over multiple trips that have spanned multiple years.
So I recommend that you bring your MagicBands with you and plan to use them on your trip. As long as your MagicBands are still linked and 'Active' in your
My Disney Experience account, your MagicBands should work perfectly for your vacation. If for any reason you have trouble with your MagicBands, head to Guest Relations or the Cast Members at the theme park entrance and they will make sure you are all set for your trip!
Please let us know if you have any other questions. T-T-F-N, ta ta for now!
