I beg to differ. Over the years the "quality" of guests at WDW has been going downhill, in all parks. People scream at kids, damage the park (if your kid is there striping the leaves off of a tree, how about you tell them to stop), litter like it's their job, have no problem standing right in front of your kid at a parade, ush past and cut in line, and do a host of other things as well. The general population of any given park at WDW on any given day has been less polite.
Sure it is not the all out war zone that many of these posts seem to make it out to be, but there has been a definate downward slide in the general plesantness of the people that are attending.
Why, I really do not have an answer.
