If you don't mind carrying the little extra weight or spending more money (or the child is carrying/buying them themselves) you could buy the blue book and the photo book. The blue book can have pics glued to the opposite page but they will stick out unless trimmed a bit. So I would use the photo one for my favorites, and the blue one for the random characters that you don't love but want to meet and get autographs/pictures......a possibility. I always just use the blue book and bring a jubilee of sharpies to choose from. Just have the sharpie picked ahead of time, instead of getting up there, handing the book to the character, then needing to rustle through your backpack, pull out the giant ziplock of Sharpies, and pick 1. Hassle for you, longer wait time for those behind you, and awkwardness for the characters sometimes.
Have a Magical Day!!!
