I agree with you on how some situations can be annoying (like a screaming kid in a restaurant) but that doesn't mean I am judging the parents, as you said. The only thing I can think of that does make me "judgy" is when folks are rude to other people and/or selfish. The basic disrespect for other humans kind of things. And by that I mean by adults, not even kids. They kind of touched on that in the Blackish episode, which I watched last night, when they were going through the FP/VIP lane past all the 'poor saps' standing in the general admission line and boasting about it. haha. It was funny because it's a comedy show, but that kind of attitude is basically what is my pet peeve. And I'm sure I'll see some of that at Disney in a way. Pushing, cutting, etc. But overall I expect people are all just trying to survive their vacation and have the best time possible and are not going to behave like that.
I actually get kind of bummed sometimes that we aren't going to have kids with us to enjoy the experience with, especially when I'm looking at MK plans. My nieces went with my sister and mom back in Feb for cheerleading and I was so bummed. For one, they didn't even invite me! haha. They didn't really plan anything, but they still had a good time. I wish I could've seen it though, instead of just hearing it afterwards. But other times I am glad we are getting to go as adults first, before we take our future kids. Consider it a preparation trip for the future!
Yesterday I watched something my Tivo recorded because I set up a Disney keyword so it records anything with the word disney in it. It was on TCM station and it was a Walt Disney show that aired in 1966 about
Disneyland. He talked about the it's a small world ride grand opening and showed a ride through. At the end they showed the Fantasy on Parade (?) and it looked really fun! Goofy got out of his broken looking car and did a little routine trying to fix it. Reindeer pulled kids out of the crowd on the sidewalks to come dance in the middle. I loved when they showed video of the crowd reactions and the kids with big smiles on their face. I mention this because this was one of those times I was a little bummed that we won't have any kids with us.
