Well this is a complicated situation as telling people when the five o'clock prade is shouldn't be attempted by anyone but a paid professional.
Though, chances are, if you're reading an internet Disneyland website, you already know more about the park than most any reasonable individual, and will be able to answer the person's question, give them additional information, give them tips and tricks about how to best solve their problem, give them detailed background information of whatever they're asking about, draw them a diagram of where they can find the "hidden mickeys," and complain for twenty minutes about how whatever they're asking about would never conform with Walt's vision.
If they are nice, they will get correct information. If they are rude, they will get incorrect information; i.e. "The three o'clock parade starts at 5 p.m. And there's no need to save a seat."
