Staggs' spontaneity remark makes perfect sense to me. I'm now able to get the fast passes I want, for the times I want, well in advance. I don't have to show up at rope drop and race somewhere, or know that if I don't come to a park until noon, it's too late to fastpass any E-ticket attractions. That allows me to treat the rest of my day with spontaneity, because I'm not longer bound by arriving so early, or rushing to a certain area of the park to start the day. I can walk in, take my time strolling down Main Street and shopping, going on other attractions, etc. I can do whatever I feel like doing, because the tough-to-get fast passes that would normally dictate my day are already taken care of. I'm entirely unsure how the old system, wherein you had no other option but to show up early and head straight for the FP kiosks, did anything but curtail spontaneity.
Example) On our last trip, we had a Space Mountain FP booked for the early afternoon. Previously, the only way to do that was to be at Magic Kingdom early. Instead, we slept in a little later that day, decided to go to EPCOT for lunch, and then made our way over to MK in the afternoon. We were able to get on SM with very little wait, then immediately start enjoying other parts of the park. Our morning was entirely spontaneous because we no longer had to worry about how early we got there in order to ride Space Mountain. Pre-magic band, we would've had only two options for SM: (1) show up early to the park, or (2) wait in a 90 minute line.
We were able to enjoy WDW immensely more this past trip than our previous trips because of the freedom the MBs provided us. Of course it sounds counterintuitive to say our extensive pre-planning allowed for greater spontaneity, but it's the case. I'd much prefer to spend time pre-planning before my vacation so that I can relax more during it, than do less planning but be forced into excessively early mornings or longer waits.
So I'm thrilled with the system. I ride the rides I want, when I want, with less time spent in line. Does that mean I spend more time seeing other things and spending more money? Yep. But I'm hardly going to say shame on Disney for that. They aren't picking my pockets during that time, I'm freely choosing to spend more, because I want to. And I'm glad for the additional time to do it.
Finally, I just want to say that this board isn't even close to representative of the majority of WDW visitors. This board is for us fanatics. It's the same thing you see on message boards for sports teams. We're the extreme. This board is full of the rope-drop types of folks, and the folks who know the ins and outs. So while magicbands may have limited the fanatics' ability to rack up FPs for the day by starting early and often, I'm betting the vaaaaast majority of visitors who weren't as knowledgable about how to take advantage of the FP system benefit much moer from the current system.
Finally part 2: It's silly to think Disney can't compute the ROI for this. To anyone saying "yeah, money spent per customer is up, but that's only because prices are up," do you really think they don't account for that variable....? Of course they do. But yeah, I'm sure Staggs is being promoted and lined up for CEO because it's failing to generate any ROI.
