Yes they have for a few years. I had made a book each year for my kids. I used the icons and graphics they have then put pictures of us meeting the characters the previous years. It is always a big hit with the characters and the cast members. They love flipping through the books.
I put the picture we take with Tinkerbell each year in as well to show my kids growth with the year under. (they wear the same style shirt in the meet) They all love seeing the pictures of them growing. Peter Pan even remembered us from the previous year due to our book and spent lots of time with my kids. Tinkerbell always does the same due to the book.
