We did this for the girls once. Made scrolls and tied them to two life size helium Mickey and Minnie balloons. I went into our local disney store and they gave me an old window display. We did it on the morning that we were leaving and had the suitcases packed in the living room.

I made some pretend vouchers/tickets for Lucie and Lady B made her a letter.
If you want to have a look at what the ticket looks like have a look in my photobucket under lucie.
