This is how it worked Nov 2022.
We took pictures at home and had them printed at Walgreens, I did 4 pictures and printed on one 4X6 picture (cheaper than passport size pics). It is smaller than a passport photo (color headshot photo 3cm tall x 2.5cm). They have photo booths at the airport, but this was easier.
The weekly pass works Monday 12:01AM to Sunday 11:59PM, that schedule worked out for our schedule. We didn't use it to get to
Disneyland since we arrived on Sunday (we just Ubered), but used it to get from Disney to Paris.
We had to buy it from the ticket booth, which didn't open until 7AM (we arrived at 6AM and had to wait 10 minutes), but it was super easy. She took our precut pictures and stuck them to the card (they have adhesive).
The card is 5 Euros + $30 Euros for the pass. It was totally worth it for us because we went to Palace of Versaille and the airport, we also got on the wrong train a few times so it was very useful to have unlimited access.
We still have our cards that we can use when we go back.
