This isn't a simple question, but I can try to tell you why it bothers me.
First, it totally changes the dynamic of the theme park vacation, introducing technical hurdles and roadblocks to what is supposed to be a carefree experience, or, as someone else put it, an escape from the real world. Way too much hassle and planning.
Second, it creates an environment which can and may lead to a vastly different experience between haves and have nots, or opt-ins and opt-outs. Artificially lengthening wait times and then selling a service to alleviate the "problem" is tantamount to extortion. No thanks, I'm not interested.
Third, as to the privacy concerns, sure, it's Disney, they're harmless, they promise this is a benign thing. Okay, fine, but there's an awful lot of money to be made with this technology. Introducing flashy wristbands (reminds me of the Silly Bands fad actually) in a theme park environment is a great way to get the public-- and our children-- to see RFID tracking in a non-threatening way.
But what happens when Disney sees the profit involved (if they haven't already) in selling this technology for use elsewhere once the public is "comfortable" with it? What happens when your child's school district demands that your son or daughter wear an RFID tracking device at all times on school property? As a society, are we comfortable with outfitting our kids with what amounts to house arrest bracelets?
Conspiracy theory or not, that's a feasible scenario, and yes, as a parent and an American citizen this technology troubles me on a deeply emotional level. And perhaps that's why (IMHO at least) people are uncomfortable with the use of this technology by a company that used to preach hope and omtimism for the future.
I'm not an expert on all things but as a consumer, I know what I feel. And this just doesn't feel right to me.
I doubt the family in the Carousel of Progress would tout the wonders of RFID tracking as one of the amazing technologies they've come to love.
