That happened to us once, there was a woman sitting on the ground near the front of the line for Voyage of the Little Mermaid. It was July, super crowded and HOT. After we waited "forever" with two small children, a large group of ADULTS (10-15) joined that lady right before it was time to go in. Due to this, we did not get into that showing (short by about 5 people in front of us)and had to return and wait again. Try explaining that to the children.
