I always tell guests the best thing to do as far as autograph books is to wait until check-in at your resort. Then while one adult is checking in (this as you know can take more than a few minutes), the other people in your party head to the hotel gift shop where they carry the official autograph book and fat pen (you must have the fat pen for the characters - it is easier for them to hold onto). This keeps the children from getting antsy while you are waiting in line to check-in.
