The casino comps system is a little different, but overall it's fairly valid. Casinos originally saw comps as a way to track high rollers and to assign them sufficient perks to retain their business, but what they quickly found was that many gamblers would gamble more (and beyond their means) in order to "earn" greater comps. There's a psychological effect at play where the gamblers get some kind of sense of self-worth from being perceived as a high roller, and thus would take more risks (ie gamble more) in order to be rated higher.
I'm not sure that will work at Disney. At it's core, gambling is a solitary pursuit and most high roller gamblers are loners. Disney is a purely family event, and adopting a pay-to-not-wait program will probably alienate those families, many of whom are stretching the budget to get to the park as is.
As far as the RFID and tracking, my objection is more to the fact that every facet of our existence within the park is being followed to maximize the amount of money they can take from us. As a corporate strategy, it's sound - but as an operating platform for a "family" company, it sucks. Disney better remember that they can't lose the humanity, and it's biggest enemy isn't Universal Studios but cynicism. Too many policies that anger people and they stop coming. If mom and dad stop coming, the kids don't get indoctrinated and then they don't come.
And for the record, as a litigator, I love RFID and member clubs and all those things that track your comings and goings. It's an excellent source of information for when I have to pry into an opponents personal life to figure out where they were and how much they have. Security tapes, key cards, all that stuff - it makes my job a lot easier: "Mr. Jones, you claim that in the days following the accident you were at home bedridden in severe pain, but your Member's Club at the local casino shows that you entered the casino at 2:31 pm and did not leave until 9:45 pm, gambling over $1250 on slot machines during that time. A review of security tapes showed you seated at a series of slots for over 7 hours, in no obvious pain and without needing any type of a break. How do you reconcile your testimony with what the evidence shows ?"
