I've been reading the older posts about the Navigo Decouverte and have checked out the official website as well. My husband and I are traveling to Paris and will most likely utilize the metro (we've been to London a few times and think the oyster pass for the tube is the best investment we've made there!)
Can anyone give me any specifics about the pictures that we'll need to take for the Navigo Decouverte? I'd like to have them ready to go. Is this strict like a passport photo in that you can't smile, background is white, etc? Thanks for your help!
