Their favorite is still the original one which has the most autographs.

My dd is 3.5, and this was our first trip with the book for her. She loved it!! I bought her 2 of the ones at Disney that hold a photo on one page and an autograph goes on the other. She got Princesses and one with Mickey. She liked that it meant spending more time with characters and she also liked that it was a routine and she knew what to do for the interaction.
