You purchase a passport book in Epcot and you have it stamped and signed by a cast member in each country. My kids love doing this as the cast member will write a message to your child in French or German, etc. You will visit the "kidcot" station to have this done. You can purchase the passports in Epcot, but I made mine at home. A few years back, someone on the Dis posted a link to make the passports at home. They were super cute! If you are interested, I can try to post it here. There were 2 kinds--one for girls with the Princesses on it and one for boys.
