Disney has announced that guests who are visiting the theme parks for just one day are now able to utilize the MyMagic+ service before their visit. This includes the ability to register at My Disney Experience online, reserve FastPass+, and purchase MagicBands on site.
In addition to this change, Disney Parks has announced that all guests will be able to add additional FastPass+ “entitlements” on the day of their visit (in addition to the three they can plan in advance).
This means once a guest has used the three scheduled FastPass+ options they can visit an in-park kiosk and reserve a fourth, and once they have used the fourth they can select another.
It is being reported that Disney is also working on a park hopper enhancement to FastPass+ that will allow guests to add utilize the FastPass+ system when they are park hopping.
