I guess it is too general to say "people acting rude".
More specifically, people running/pushing to get to the front of a line/show/etc.
People smoking outside of the designated smoking areas (it isn't that hard to find the designated areas. And some places I see people smoking are very obviously not allowed). Wish this rule was enforced more at the parks.
People in larger groups standing around and blocking traffic-ways.
Most of my pet peeves are just things you have to deal with when there are large crowds, but overall the positive experiences far outweigh the occasional annoyances.
