One more thing: The reason Robespierre gave you 2.05 as the price of a single ticket is because that is what it would cost you to get from zone 3 (where you're staying) to central Paris (zone 1). The 1.40 price is for anywhere within zones 1-2.

Just to recap, here's everything you'll need:

o 3-Zone <i>Carte Orange</i>
o Single ticket CDG - Le Blanc Mesnil
o 3-Zone <i>Mobilis</i> (for Monday)
o Single ticket Asni&egrave;res - CDG (for Tuesday)

<i>Bon voyage!</i>

Thank you VERY, VERY much! Y'all (yes, I live in Texas) are GREAT! I really appreciate it!

<b>correction</b>:
The Carte Orange is good for Sunday-Saturday
- no, it is valid <b>Monday through Sunday</b>

Yes, I was wrong about the validity days for the Carte Orange. I knew better (mental lapse).

Thanks everyone. I learned a lot by just reading your responses.
