Just a suggestion. You can also bring along a mickey t shirt (or any tshirt). The characters will also sign this with a permanent pen. We did this on our cruise and even though my son outgrew the shirt, it is a better keepsake than the autograph book. What I did was bring the shirt up to the main desk and asked them if they could get all the characters to sign it. At the end of the cruise I got it back and it was all signed. My son thought this was the best thing ever.
