I have read on the DIS boards about the homemade passports for Epcot, as well as the passports you can buy at Disneyworld, but what are the autograph books for? Is that for the other parks, especially MK? Do you just walk up to the character (CM) in MK and ask for an autograph?
I'm new to all this and going with 3 nephews in January, so I'd like to do either the autograph book or the passport.
