I'm going to try to stay away from the "I can feel like a kid" notion. Even though it's true for me, so many others on this thread have said that as well as I could...
I keep seeing people write things like "I can go to so and so for...and so and so for...but I can go to WDW and get everything." That's so much of it for me; Disney is the total package. It's appealing to me to leave the rest of the world behind and just have fun. There's so much to see, do, and experience for everyone.
Another thing for me is that Disney's in the details. From attraction theming to immersive resorts to little in-jokes all over the place, WDW is all about making sure every little detail is taken care of. I can walk through an area or ride an attraction multiple times and see something (even a small detail) that's new every time.
WDW is also about excellence and creativity. For all the debating and sharing of opinions (and complaining), nothing is done without a high standard of excellence at WDW. Disney inspires me creatively. As someone whose job -- and life -- largely involves creativity, I am constantly renewed and invigorated creatively when I visit WDW.
OK, there's my essay on this topic. Sorry it's so long...
