My first Disney experience was in the summer on 1970 when our family loaded up a green station wagon, drove all the way across the country, visited relatives on the farm and camped at KOA campgrounds en route, and went to
Disneyland for a day (hmmm, sound like a movie plot?). It's funny what you remember from long-ago trips when you were young. One thing that stuck in my head was the sight of a visitor standing at the central hub shoveling popcorn into his mouth getting only about half of it in his mouth with the other half falling on the ground. Standing right next to him like a soldier at attention was a CM with a broom and dust pan. Every time a handful of popcorn landed on the ground, the CM would sweep it up, and then wait at attention for the next handful.
Once could view this two ways. In the "good old days", Disney invested enough in personnel so that each visitor could have a personal valet to clean up his/her mess. Or maybe you could view this as evidence that park visitors are entitled pigs. This may not be a popular post, but the truth is that if you see a piles of trash lying around the parks, it is because some visitor put it there. Do you ever pick up garbage you see lying around? Do you ever wipe off the bathroom counter with your paper towel when you are done? Do you ever help out a CM? Do you ever leave the park nicer than the way you found it? Or should you not be expected to do these things because you are on vacation?
