You’re both kind of right.
I’ll cue the broken record, because even though
@marni1971 and I have said this many times, it’s helpful to remember why FP+ exists. Before Uni built Potter, Disney believed the theme park market had topped out. They decided they owned the market, focused on selling DVC, and comfortably settled into what they called a “Blue Ocean” strategy of cost-cutting and minimal maintenance (even though that’s not what a Blue Ocean business plan actually means).
Fastplus + and its overall NextGen system were concocted as ways to spread existing crowds to existing attractions, in hopes Disney wouldn’t have to build anything new. You don’t have to take my word for it: execs announced the strategy at shareholder meetings. Iger shilled MagicBands as a new source of income, saying the company expected merch sales to increase as guests mindlessly tapped their bracelets without paying attention to how much they were spending. Again, this is on record.
That’s why FP+ and MagicBands exist. There’s no bigger reason for magic, pixie dust, improved guest experience, or anything other claims the Mommy Bloggers ate up from Disney’s marketing spin rooms.
Unfortunately, Disney changed its operating procedures to exploit FP+ reservations, and often runs attractions at sub-optimal levels to artificially create long queues that the day’s attendance should not demand. This is why you can go to the MK on a slow day and still stand in 45-minute lines.
The experiment was also a failure, and the system was never expanded to the other worldwide resorts as originally planned.
Fortunately for us fans, the crowds did not disperse, attendance actually rose, and Uni built Potter! Now we have New FL and Pandora, with many more investments to come — including Tron.
