While my daughter was getting her photograph taken with Minnie (her favourite character). I started to look at the back drop, a very busy mural / set. The under lying theme here is communications. There is satellite dishes beaming out signals, computers receiving data, characters texting and using a tin can phone (updated cup and string version).
I then thought. There is bound to be a Hidden Mickey here.
On the side of the computer console is a classic Hidden Mickey.
