This has been a very intersting thread to read. We usually visit downtown disney once per trip, and I've always been amazed at the amount of people that are at the mcdonalds. I mean think about it, if you drove to disney, you probably passed hundreds of them on the way, if you flew, there was probably one at one of the airports you went through, or you drove by several on the way to the airport. Plus, you probably live within 2 or 3 miles of one or more.
So I never understood why in the world it was so busy. I guessed maybe visitors from other countries.
I've visited Las Vegas once (everyone says it's like Disney for adults, but I didn't think so, I'd rather go to the real disney because that's for adults too, but anyway), and there was a mcdonalds we saw on the strip, and it was packed. Again, didn't understand why, because most people were probably tourists.
Maybe there is a desire to say, "I ate at not just any Mcdonalds, but the Disney (or vegas, or wherever) mcdonalds."
I also understand the rational of taking a kid there. I can only imagine what I would have been like at 5 years old seeing McDonalds at Disneyworld. No amount of reasoning would make me not want to go at that age.
All that being said, there are just people who probably drove by hundreds on the way, and live within a few miles, and for some reason, they just really want to go there.
Nothing wrong with it, I can't imagine that i would ever want to, but more power to you if you do.
