Quit spending money on anything Disney. Period. Parks, merchandise, movies, Disney +, everything. Quit engaging in anything Disney related - this includes internet forums, it really does. Have to drive the data so that it shows a decrease in interest. Same with NOT clicking on any news articles, just as with any other topic, every click shows interest. Don't like celebrity Z, every time you click on an article about Z it registers as 'interested in Z' and you'll keep seeing articles about Z.
So until you happen to see the headlines you've been wishing for, you don't read the article. Common wished for moves by Disney: "Disney to restore all entertainment" "will spend gazillions on new attractions", "open 5th gate", "shift more money to US parks" Wishes Fireworks Show to Return" "Marvel to be Removed!" "No more IP!"
"New CEO hired who is totally theme park focused who idolizes Walt and will reinstall Walt's vision" You know, that sort of thing.
Its the only way. But you have to get tens of millions, not just the 18 million who were going every year, but the tens of millions PLANNING on going to go along with you.
Not going to happen. Maybe that's too strong, lets say "very unlikely to happen." The tens of millions who weren't there 10, 20, 30, etc years ago don't know what they don't know, don't know what was (from personal experience) and are going there to visit what IS. Every year millions of new first time visitors go to visit What Is.
So, acceptance. Accept that the Disney you might have loved is gone and likely not returning. Accept that your personal Disney era is over. Then decide to go or not.
I'm not at the end of my personal Disney era yet. I still find value in spending some days in a place with happy music, generally happy often huge crowds of people, people gathered in one place seeking more or less the same things. There is a bond, an energy, a vitality that exists in that, that resonates through the spirit, the core. Its similar to any large event, and sports arena atmosphere. We've been to Disney on a couple of its busiest days of the year. Packed in tighter than a fraternity party on Greek Week, and it was marvelous and I recommend it, at least once.
Again, the only way to make the things you and so many of us seek to be important again to the company is have tens of millions of people around the world to just cease all Disney related interaction. Since the odds are against that, have to decide how much more you want to pound your head against the wall, how much digital ink to spill complaining and wishing, how much of your spirit to invest. Maybe that's the fun part of a great number of people in forums: the constant arguing, thought experiments, what ifs, whatever. But in the for Disney: $$ talks, b.s. walks. Just a fact of life.
I'll be there in January. Going to be very interesting to say the least, and I suspect under my criteria, fun.
All the best!
