Joe, I think a lot of people have the same concerns as you, and they are valid concerns... However, if my feelings are right, I think I can hopefully remove some of the concerns with the meet and greet FP+...

Let's say Mickey meets in Character Spot in Epcot... One show room will be for those who do not have FP+ options, one show room will be for those with FP+... Why split them? Well, the FP+ people will have a Mickey who knows your child's name already due to the magic band... Mickey will greet your child by name (which, sorry, I find creepy not magical)... The people without FP will not get the talking Mickey, or if they do, he will not be greeting by name...

Imagine Mickey saying, "Hello Little Johnny, how are you today?" Then not knowing the next child's name.... The second child may get upset cause Mickey knew Johnny but not Jimmy... Then you get irate parents, complaints to guest services, freebies handed out, and unhappy guests...
