Actually I went to disney in 2005 and my little brothers sandle got stuck in the esculator, it part of his sandle into the esculator and would have pulled his foot in if my dad hadnt wrestled with it. Disney offered us a replacement set of sandles but didnt mention about closing the esculator or any other steps to stop someone getting hurt ie a small child.
its good to hear they are closing down esculators
If his sandal got caught in it, it was because it wasn't working properly. It was a bug rather than a feature.
