Magic is in the eyes of the beholder. What makes Disneyworld/
Disneyland magical for me may not be what does it for you.
For some, it is the major attractions. For others, the theming. I imagine that the depth of the magic is relevant to how often you go. On your first trip, you might be aware of your surroundings, and how well they are themed, but you are so busy trying to find your way around, and running from attraction to attraction that the majority doesn't sink in.
At the end of the day, and you have experienced 75% of the attractions at the Magic Kingdom, and you trip does not allow any more time there, you say to yourself, I HAVE TO GO BACK. I want to see the rest.
On your second trip, you hit your favorites from last time, and then the discovery happens. You experience things you passed over on your first trip. You didn't have time for the enchanted Tiki Room, but go now. And you are amazed that every flower and face on the totem poles sings along. All of a sudden you notice the music on Main Street matches the timing of the area. And that it changes when you cross over into Adventureland. Wait, what's this? There is a drum and fife corps playing in Liberty Square. And they get some of the kids in the crowd to march along. Then you go into Hall of President's and smile to yourself when you see the President's casually chatting among themselves while roll call is made.
On the next of your now annual trips, you stop in Town Square and sit on one of the vintage benches, soaking up the atmosphere. You are so happy just to "be there". It's amazing, you think to yourself, the place looks like it was built yesterday.

It's a package deal. It takes great depth in the experience to create magic. This is what current management fails to understand. They peel away layers of this depth to save money, destroying the very thing that created them.
The story gives the place context and gives a place meaning. And that gives the place magic.
A well told story has many levels, much as a well made park does. Everytime you read a good story you get something new from it. Everytime, yes, everytime I visit a "good" park I get something new from it.
Does all this cost more money. Yes. It also costs time, energy, caring, talent, passion, and desire.
