Just trying to simply get across the fact that one day Disney decided to charge for no exp and hopping.
But why is that a problem? One day, everyone had to pay for something not everyone used. Next day, people who weren't going to use the no exp and hopping weren't paying for it, so they were happier. People who wanted to use no exp and hopping could still get it if they valued it at what Disney's charging, or they got a discount on a regular ticket, so they were fine. And Disney, presumably, could end up charging more for a particular perk while keeping the basic price down for those who weren't interested or were willing to go without those perks. Win-win for everybody.
I don't like nickle-and-diming when I feel like it exists to hide costs. For instance, a "resort" fee that
everyone who stays in a hotel has to pay, whether they plan to use the facilities or not. But when it's for parking, and clearly posted with the regular price, that doesn't bother me much, even though I always drive and will have to pay it, because it's essentially a discount for people who aren't using a particular perk. It's paying for two different things, not a hidden charge I have to pay no matter what.
Hotels charge for parking because space is at a premium -- if space isn't at a premium, they just build a bigger parking lot, because where there's space people either don't stay where they have to pay for parking or they just park down the street. Disney initially didn't charge extra for park hopping because people would have just stuck with the Magic Kingdom or wherever they were used to going. Disney wanted people to get to the other parks and so they encouraged park hopping. But once all four parks became reasonably popular for themselves, then park hopping became a perk in itself -- a perk that most people didn't use, so Disney pulled it out of the basic ticket and charged for it separately.
No expiration, OTOH, was a perk few people ever used that became pertinent when Disney worked out crowd predictions, so, again, charging a separate fee for that years after it was "bundled" into a regular ticket made sense. Disney wouldn't have tons of tickets floating around in the aether that might or might not be used any one year, while people who made the effort to buy a non-expiration feature were more likely to make use of them at some point. People who didn't use the non-expiration feature got a discount, while Disney had fewer variables to worry about.
Change is inevitable. With a well-run business, it's also logical, and usually aimed to make the most profit by pleasing the most people. Disney is as mass market as it gets, and only artisans are likely to aim for pleasing a tiny minority at the cost of pleasing a larger group.
