We like to purchase a small photo album from Michaels. I purchase some Disney stickers from the scrapbooking section to decorate the front. We do all the autographs on the left side page, and then when we get back, we put a picture of my daughter with the character getting the autograph on the right side page. This doesn't necessarily make it cheaper, but my daughter loves going through the books looking at her pictures long after the vacation is over.
