1. But don't plenty of folks aready buy that service in the form of touring plans? Sorry, I just see this as Disney's attempt to get everyone on board the touring plans formula.
2. It will take some choice out of the touring WDW picture, but conversely, it will take some of the thinking out of it. You get off a ride, and your phone will tell you where to go next. You will - ideally - hop from attraction to attraction with only a FP type wait.
My guess is that in practice, the waits will be slightly longe than FP of the past, but lower than standby waits.
Mind, I do think there's something slightly creepy about WDW tracking our movements throughout the park.
Disney is hardly alone, ever heard of 'video mining'? What about the proposal to have data recorders in all autos? ("On Star", for a start)
Oh, and how about that handy smart phone you carry around?
