I really dont see why everyone is so worried about this location stuff and people actually bringing in child molestation into this new MagicBand discussion part.
Im bigtime into privacy, but I dont see the problem with Disney being able to locate you if they want based on when you buy something or check in at an attraction. Its opening up a new world of what can be done with this MagicBand, like people say it seems like they are planning scavengerhunts or something as well. Its a good move of Disney to make payments as easy as just taping the terminals. It will be so much easier for people to use more money at the parks.
And people, Disney has so much security (hidden too) and videocameras all over the parks, they can find you anyway if they wanted to. Cameras are hidden everywhere, its always fun to point them out and find new ones at parks. My favourite one is in a Splash Mountain sign...
And with this FP+, you should only be able to make 3 reservations? So there should be possibilities to get regular FP as well for the people who visit without knowing of this system. I dont really see the problem. People will have the possibility to at least do three of their favourite rides when they arrive in Disney. Now when the parks also strictly enforce the times on FP, its not too much FP lines if you go at the right times.
