What is your definition of that Disney magic? Or what has ruined it?
If someone asked me why the magic is gone, I would tell them a couple of things:
1. The creativity in new attractions. Even the IP ones, there was heart and soul poured into them. The story was prioritized over the namesake program. Now they shoehorn IP everywhere regardless of sense.. they are banking on your understanding of the IP first before you get to enjoy the ride to it's full extent.. and the last major (or generally) non-IP attraction was Expedition Everest in 2006.
2. The price gouging. Instead of expanding to meet demand, they are increasing prices and diminishing goodwill by removing what used to be part of admission (magic express, fastpass).
3. The kindness, happiness, and random encounters with CMs & people at Disneyland aren't what they used to be. A lot of CM's and visitors are understandably miserable.
4. The maintenance. Broken effects hardly stayed broken, but now they do.
I wont mention other things like reservations and Genie+, but it should be implied that they've helped make the guest experience worse.
I would say all these things, except number three. Additionally, for me personally, I would also add a significant drop in interest in going in general. That’s number one for me, and I feel that even if numbers one, two, and four weren’t happening, I still wouldn’t be going as much.
Perspective and personal experiences are important to consider. I’m privileged because I’ve not only always lived within a 45-minute drive to a Disney resort, Disneyland specifically, but all of my visits as a child, and there were many, were free because my uncle was head of Walt Disney Studios security (he’s retired now, but can still sign us in) and he would sign us in. If there was a bigger party of us going, for example, if we invited our friends, my uncle would get some of his work buddies to come to the parks so we could all get free entrance. Disneyland was never a vacation for us and my mom only had to save enough money for food and souvenirs for me and my siblings. I’ve also gotten the chance to experience a lot of things that average Disney fans don’t, simply because of my uncle and living in Southern California. I’ve been to a number of exclusive screenings and events put on by Disney and I’ve met many famous people within the company over the years that I wouldn’t have been able to do with my uncle’s access. I have memories of being a kid and hanging out at the Walt Disney Studios in Burbank for no particular reason and having lunch with some of the people that worked there at the cafeteria on campus. I had a unique Disney childhood, for the most part.
Outside of the exclusive things, whenever a new Disney movie came out, my mom would take us to see it at the El Capitan Theatre in Hollywood because there was always some sort of show or extra offering that came with the movie (afternoon tea with the Disney princesses and Minnie Mouse was the offering for Princess Diaries, for example). I was a D23 member during its first few years and went to a lot of those special events here in Southern California. I was an AP for some years and was a CM. When I was a USC student, I got the chance to hear Joe Rohde speak on campus a few years ago. I’ve said this before, but Southern California has felt more like a Disney World to me, as a Walt Disney fan, which contributes to the reasons why a WDW vacation doesn’t interest me. No Disney Resort does.
To wrap this post up, I’ve had my fill of Disney. I’ve gotten to see and do a lot Disney things throughout my 30 years of life, and I reached the point where I’ve had enough, moved on, and now prioritize other things, particularly travel. I had always wanted to travel the world, but my parents weren’t interested, and they couldn’t afford it even if they were. I told myself that when I graduated from college, I would leave the country for the first time, and that’s what I did in 2017 (I went to Ireland and Northern Ireland). I’ve been to five other states and six other countries since then, with no plans to stop. I let my AP lapse in 2019 and I don’t miss it. I like to keep up with what’s happening because I haven’t 100% cut off all my visits and because I enjoy it. I go maybe once or twice a year now, sometimes every other year, which I’m happy about.
