Hello Kathy, and welcome to planDisney! How exciting that you'll be visiting the "Happiest Place on Earth" in May!
It will depend on what type of MagicBand you have since only
MagicBand+ is currently supported at the
Disneyland Resort. MagicBand and MagicBand 2 are not supported at the Disneyland Resort, and cannot be linked to the
Disneyland app for admission or other experiences.
If you find that you do have a MagicBand+ on hand already, that's great news! It has a ton of great features such as interacting during certain
nighttime spectaculars, and you can
discover interactions with the new Disney100 statue and medallions located throughout the parks and the
Downtown Disney District! If you're in need of a MagicBand+, there are plenty of places to shop for your new accessory such as the
shopDisney site prior to your trip, or during your trip at the
World of Disney store!
I hope this information was helpful for your trip planning Kathy, if you have any other questions, please do not hesitate to come back to planDisney, we're here to help!
Have a magical day!
Melissa
