5. People Talking Over the Narration
If you are one of the people that does this, stop it! Seriously! Not a single person standing in that line did so in order to hear you and your group deliver the lines. Let people enjoy the attractions the way they are meant to be enjoyed – without your input! If you absolutely insist on showing off that you know all the narration to the Haunted Mansion – which thousands of other people can boast, by the way – do it in line before going on the attraction or better yet, after you get off.
