A couple of years ago my son lost his brand new Pal Mickey on Star Tours. He had left it under the seat. We went back to get it. When we got there we ran into someone who saw it. They had gone back to get something that they forgot. It turns out someone gave it to a CM who then took it and put it at the exit doors. From there somebody else picked it up and my son's day was ruined. He had only had got it that day and was very upset. We went to Lost and Found and nobody turned it in, and they couldn't help us. Well, later that day my wife was talking to another CM, she was curious why my son was so unhappy. Well my wife related the story to her about the Pal Mickey. She said wait a minute, went into talk to a supervisor. She came out with a slip for us to bring to the store at our hotel (POR) to get the Pal Mickey replaced for free. We couldn't thank her enough for going above and beyond. It really saved our vacation, and renewed our belief in the Magic of Disney.
I am very sorry for the loss of your Pal Mickey especially having been in that situation myself. I wish yours could have had as happy an ending as ours.
