Disney theme parks might be a place where dreams come true for guests, but they can also be a nightmare for the staff. The behavior of some visitors is so high-maintenance that staff has a special name for them. If a visitor is particularly rude or disruptive, staff will refer to them as a "treasured guest." Disney has rules against employees using negative or insulting language in front of customers. So the staff has come up with a more diplomatic name for the worst visitors.
