It sounds like on the 27th itself from the article. Looks like it goes live that day on
MDE,
ShopDisney, and in Parks.
Its also not going to be as expensive as originally thought. I had read pricing was around $50 at some point, but it looks like $35 with discounts for ordering before your trip on MDE.
If you’re planning to get one or even collect some, don’t forget that Disney Resort hotel guests may purchase MagicBand+ online at special prices before their arrival. Annual Passholder discounts will also be available on MagicBand+. All guests can buy MagicBand+ at select stores across Walt Disney World and online at shopDisney, starting at $34.99.
Something else to keep in mind with the MagicBand+ is it may not be something everyone in the group will want since its going to be more complicated than a traditional MB. I wouldn't recommend it for younger kids or non techie people. They're going to need to be paired with a device/MDE app it sounds like and charged. I wonder how long a charge will hold for?
Before you embark on these experiences, make sure your MagicBand+ is charged, up to date and paired to your device.
