Wow!!! I have no idea how I missed this until now, but I read the whole thing in the wee hours of this morning. I must say I feel a kinship to you, however I grew up in Northern CA and lived there all my life until about three years ago now, so substitute disney world with
disneyland (the original magic kingdom bye the way, if you're interested in that piece of trivia), and my early disney history is a lot like yours.
I will say that I went for the first time when I was 8 and have been there numerous (probably about 50-60 times) since then.
You are WAY ahead of me at disney world however!! I only went there for the first time last September.
