I have used the CM books as well, but I've taken a different approach. I take the whole book with no decorations into the parks. The first time we used them, I carried 3! I'm a bit of a scrapbook psycho, so I also carried the Round Tip Pens in a variety of colors. I just had to match the characters!
I took photos of the children getting autographs and with the characters (of course!). I allowed characters to sign all pages, and encouraged them to share a page if they were going to be in the same photo. When I returned home and got my photos back, I inserted extra pages into the album between the autographed pages. That way I could put the character's photo on the page facing the autograph. I added some enhancements and a page protector and called it done!
BTW, CM is coming out with a completely new line of Disney stuff on June 1, and it's adorable!!!
LOVE your adorable pages!
