Paper FastPasses done at Disney's Magic Kingdom
Jan 14, 2014

Beginning today, January 14, paper FastPasses will not be available at the Magic Kingdom. All Magic Kingdom guests will now be able to utilize FastPass+; previously, it had only been available to Disney resort guests. Offsite guests will need to visit a MyMagic+ kiosk to make their selections when they arrive at the park. If they need to modify any of those selections, that will need to be done at the kiosks as well. Offsite guests will not receive MagicBands, but will use their tickets instead. Walt Disney World resort guests will continue to be able to make their FastPass+ selections in advance and will be able to use the My Disney Experience app or website to make and modify their selections.

In addition to the Magic Kingdom, Animal Kingdom has also switched to just FastPass+. Hollywood Studios and Epcot are expected to make the switch in the next couple of months.
