How many pages are needed in my autograph book?

[SUZI]

Hello Everyone!
I have home-made autograph books for my children and was curious approximately how many pages I should have?

I am printing them on the computer, and each page will look the same (there won't be a special page for each character)

My oldest is 5 and we are only going to one character meal. About how many pages have you all filled in the past?

Thanks for your help!
