I lost my middle DS right outside Mexico in Epcot when he was 3. It was pitch black. We had gone to the restroom, came down the stair holding hands, I let go of him to, literally, grab the stroller and he was gone. I called his name - frantically, I am sure - and 3 "tourists" - 2 men and a middle-aged lady - materialized in front of me within 10 seconds. They asked his age, name and shirt color and scattered in different directions while a sweet young lady working at the CS there, gave me a drink and sat with me. The lady found him and returned carrying him, but the other two made it back to me with the good news before she did. I still have no idea what he was doing but he'd made it all the way across the main bridge into FW. I had taught him, if lost, he should look for a white cast member name tag or a mom - someone else with young kids. Since she had neither, he was quite stubborn and wouldn't come with her at first, LOL, until she called him by name and said his mommy was worried about him. She handed him over, gave me a hug and the three of them melted away again into the crowd. Amazing. I will always be so grateful for their quick action. Definitely, they have the lost child scenario down to a science!
