On one trip to the World we decided to meet the characters at Epcot. The line was GINORMOUS! At least a 30 mintue wait, more if you take into account character breaks. Anyways I saw that line and knew my son would never, ever, be able to handle it, I also knew that if I tried to explain that the line was too long he'd freak. I approached a CM and showed him my son's GAC. I said "I'm not sure if I can use this here..." He smiled and said, "No problem. Come on, we'll get your son taken care of." He took me and my son to the side near the front of line (but not on it). He went and explained to the family at the front that due to special circumstances my son would go next and they'd be right behind him, he then gave the two kids pins from his lanyards for being so nice. The parents smiled at me and mouthed "go ahead." It pays to use the GAC when needed. HAd the line been shorter I wouldn't have used the card.
