Getting around Paris takes patience and skill. It took me a few days before I got the hang of it. My cousins had to put up with my constant backtracking and fuzzy navigation, but they had no other choice but to go where I went.
Aside from the labyrinth that we had to put up with, using the subway is not cheap. It costs 1.50 euro per ticket (about P90). That's more expensive than the New York subway ($1.50 or P70). What most people don't know is there is such a thing as a carnet (car-nay) which is basically a 'book' of 10 tickets. You can purchase this at any Paris subway station. During my last trip, a carnet costs 11 euro, or 1.10 euro per ticket. We saved 40 cents per ticket. Not bad right? To buy a carnet, say 'Un carnet sil vous plait' (un car-nay see voo play) to the nice French person inside the ticket booth. Hope you find this helpful!
