This is perhaps a little different, but it was fun to make and DS enjoyed it (this was 5 or 6 yrs. ago, as DS is now 8):
I made a booklet for DS. Basically, it was a story book of "trip rules" but had fun, informational things for him. I had Disney's Print Artist, or Magic Artist Studio, or something like that -- graphics software. I made the booklet in story sequence from the time we left home that first morning until we were at WDW (we flew). It was quite simple -- I wasn't trying to be an author. It wtarted with: "Phillip will wake up. Mr. Moon will be out. Phillip, Mommy and Daddy will drive to the airport. We will ride in an airplane. Phillip gets to ride in his car seat. The pilot will turn on a special light that says Phillip can't get out of his seat. May not kick the back of the seat [in front of you], etc." Then for once we were at WDW, things like: "Phillip will ride in buses. Mickey Mouse Magic will keep Phillip safe from dark places or loud noises. Donald Duck says to drink lots of water. Goofy says to let Mommy and Daddy put sunscreen on you." Stuff like that. Each sentence was a page, and I did some sort of Disney character graphic appropriate to the sentence. I laminated the pages and held them together with book rings. Now it's a keepsake for him and he still pulls it out and looks at it.
