Disney eliminated enough free parking to keep the casual visits under control. And, for better or worse, Disney is capitalistic enough that if you're willing to shell out enough cash, you can have that no block out day pass with free parking.
As for Universal's top tier pass, I don't think we've seen it yet. They'll probably roll out a pass that includes parking and has no block out days in about a year's time, after the initial Potter rush has come and gone.
Ok, now we're getting into per capita spending, and that's an entirely different topic. Suffice it to say that the ideal theme park guest is a tourist who stays at a local hotel, preferably one owned by the theme park, spends his entire day at the park, eating at least 3 meals there, and leaves with a couple of bags of merchandise. This is the customer all the parks are after because they get the most revenue out of him for the amount of resources they have to expend. He is the golden goose.
The locals are fillers. They use up just as many resources as the tourist, but they don't spend nearly as much money while in the park. I certainly notice that I tend to be less careful about the amount of money I spend while I'm on vacation vs when I'm visiting a local park. The parks need the locals for when the tourists don't come.
So what Universal is really telling you is, "Thank you for supporting us during a time when we couldn't get the big tourist dollars. But now that Wizarding World is opening, the tourists will be coming and we don't need you any more. Run along and find something else to do."
Disney did pretty much the same thing after they straightened out California Adventure. They sent annual pass prices into the stratosphere. But the funny thing is, locals kept coming. They keep raising prices and still, we keep coming.
Universal has no doubt seen this and figures they can do whatever they want to the locals and they'll keep coming. Don't like what they're doing? Stop going. It's the only weapon you have.
These big conglomerates have no loyalty except to the almighty dollar, and not to the dollar you might spend next year if they keep you happy, to the dollar you're going to spend today.
Now, if you'll excuse me, I'm off to Disneyland.
