But they do now, and will continue to, sell/share more general data with marketers and third-parties. That will be a key component of NextGen's profit-generating side.
. . .
I want better maintenance and new, fresh attractions. Period. No need to reinvent the wheel, or fix what ain't broke.
I think you underestimate how much generalized guest data is worth, and furthermore, why Disney would part with data which is proprietary in the sense that it involves details of park operations that Mickey might not necessarily want telegraphed to the outside world.
Disney has been collecting such proprietary data for decades—in the form of daily ride counts, and guest satisfaction surveys, as well as how many plush Poohs are sold over Piglet each year. Ride counts at CBJ, Pooh's sold, dinning reservations at Le Cellier, . . . so much of this data is Disney specific, and has little value for the outside larger marketing world.
NextGen is a game that offers perks. Plain and simple, get guests hooked on making fast pass reservations months ahead of time, and whatever else Disney can cook up. Making the paperwork at the parks smoother is where the money will be made, especially allowing teenagers with RFID bracelets to run amok buying churros and plush Merida dolls.
We all know what you and WDW1974 want (and what the rest of us would like), a couple E Tickets added to each park, and the proverbial fresh coat of paint. Well, slamming NextGen won't make this come any faster as I think NextGen is going to catch on with seasonal guests big time, and the money is already spent.
APers already know how to smooze the system, and they don't like seeing this new group of premium guests getting perks they won't, while having fun doing it. I'm all for everybody being on equal footing, but I've also enjoyed Front of Line Passes and more perks than the vast majority of guests, so I think it is OK to let everybody have a similar sort of fun.
Eventually, though, total ride capacity issues at MK, and other Disney parks, will catch up with Burbank due to steady attendance growth and a relative lack of attractions.
