I chose poorly.
Magic Kingdom is a zoo. Do people just pull their kids out of school to come here? Getting food seems an impossible proposition right now, but I don't want to leave until I use my Space Mountain Fast Pass.
More than the number of people, the thing I notice most is the range of parenting ability. Some people really suck at it. Those are the ones you notice the most. But if you look, you do see the good ones, and they make me smile. For every kid getting yelled at, there is one having a moment with mom and/or dad.
And come to think of it, the same is true for other relationships too. There are couples of all ages who are assholes to each other, while others are also making moments.
It just goes to show that the fantasy environment can't compensate for your perception of the world.
