The latest edition to MyMagic+ features is on-ride video. The first attraction to offer this is The Twilight Zone Tower of Terror in Disney's Hollywood Studios. For now Disney says the feature is only available to guests with Magic Bands and Memory Maker liked to their My Disney Experience profile.
This feature has been rumored for many rides in the past, like a video of the ghosts hanging out in your Doom Buggy in the Haunted Mansion. The video package you receive is pretty cool so I'm looking forward to more attractions being rolled out.
