Carte Orange or Mobilis
 

I've tried to wade through all the Carte Orange postings and I'm sure I'm just dim, but I have to ask. We arrive on a Thursday and leave on the following Wednesday, so it is probably not cost efficient to buy the CO, as we will not be able to use it on the Friday & Saturday? Is the Mobilis an good option? Thanks very much!

The Mobilis is certainly a good option if you use it enough, otherwise it isn't. I think it's about 5,3 euro for all day bus+RER+metro in zones 1-2, so that's pretty good. Some folks don't use it that much as they just walk around a lot and buy carnets.

Nothing is written in stone as to what is a good option for everyone because it depends how much you use it. It's just math -- find out the cost and know your own patterns and how much you like to use public transportation. People obsess over a few euro cost on Paris metro ticket options or passes more than about anything else, it seems, and it really doesn't matter that much about one option vs. another.

Here's the breakdown:

thanks, Christina, and thanks, Robespierre (you've obviously chilled a lot since the Revolution!)

Actually, I get chopped regularly right here at Fodor's ;)
