That was great! I especially liked these parts:
The crowds are there for the same reason you are, but that last 1% will threaten to ruin it for you. There are so many people pushing strollers around DisneyWorld and trying to set good examples for their children and just having a good time in general, that Disney does seem like the friendliest place on earth. You'll make new friends standing around in line. You'll meet people from all over the country and the world. You'll see that all kids are mostly alike, no matter their geographic or family differences.
But then there will be that last 1% who are still the center of their own worlds who will want to ruin it for everyone. They're the ones who'll stand up in front of your three year old child, blocking their view for a show they were very excited to see. They're the ones who'll run you over to get one place ahead in line, thus saving themselves a whopping thirty seconds while proving what a jerk they are.
Remind yourself that they're the minority, that humanity is awful, and that there's nothing you can do about it. Stay calm and carry on and all that.
Remember that when your fellow geeks in San Diego start doing questionable things, too. The rest of them are friendly and often outgoing. It's an annual convention of like-minded people, many of whom don't get to talk to that many people about their obsessions or hobbies.
and especially this:
Disney Geeks are Geeks, too. There are people who really get into it. They go there multiple times a year. They obsess over the most minute details of the park, from the seating capacity of a given ride to the best time to catch the most elaborate shows. Don't let them judge you for liking comics while they chase imaginary princesses and furry costumes around.
