Paris Metro's pass for two weeks

I'm pretty sure you will need to recharge the card for a second week. According to the RATP site, the recommended dimensions for the photo are 25x30mm (1x1.2 inches). I think any type of paper will be acceptable.

I think you'll have to buy it again at the end of the second week, but it's the kind of thing it's worth asking at the ticket office.

You buy the pass and then you have to put it together. There are instructions. You attach your photo and write your name (as it appears on other photo ID) and then you put it in its hard plastic case. The card is forever - at least until they replace it with something else, someday. You need a photo that is small enough for the space on the card - 1.25" high and 1" wide. I used a photocopier to reduce a passport photo and that worked fine - color printer with regular copier paper. The larger metro stations all sell them - not sure about the smaller ones. After you have the card put together, you go back and buy a week. You can ask when you get it if you can buy two weeks. I think maybe not. But you can easily add a week at any metro station on Sunday evening - better than waiting until Monday morning. You should probably plan to get the card the Sunday before - just because there won't be long lines at the metro stations. Then you'll be ready to go first thing Monday morning. I loved using it, didn't have to keep track of the little tickets. At many stations, there are pass-only lines, which saves time in rush hour. Also, you don't have to take it out of your purse - if that's where you are keeping it. You'll see all the women just passing their handbags over the machine readers.

Thanks Philip, Tim and Chani. I will print out and reduce my passport photo. It's really great to know that I can put out my question, whatever it is and have it answered by people like yourselves. Thank you.
