Here's a photo of some of the things I kept from our Disney holidays:
I made sure to keep one of each size (and therefore colour) of bag, and I kept our park maps, tickets and fast passes. Also there is the letter and 'signed' photograph I got when I wrote to Mickey Mouse after my visit, plus my autograph books. On top there's a couple of toys I got; there's plenty more in the loft, but like I said in the book, some of it is broken etc. so I don't want to disturb it. I basically have everything to do with our trips there.
Here's a video with the parade song that I love so much:
