Your website is exactly what we were looking for. Thank you. We arrive this coming Sunday and will be staying 1 week. We want to purchase
navigo Decoverte cards. Can we purchase them at local Tabac shops? Do you think the Invalide Metro station is large enough to have a manned window for purchasing this? How late are the windows manned? We get in early Sunday afternoon and could wak to the station if the window is open to purchase our cards Sunday afternoon, if that makes sense. So sorry for all the questions, just trying to get all my answers before we leave on Saturday.

Thanks in advance,
