Paris Mobilis--ok for RER from CDG airport?
 

I am trying to find out if the Mobilis pass is good on the RER B train from CDG airport to Paris. In the RATP website, I found that (translated from French to English by internet translation site) "Mobilis enables you to travel, within the limit of the zones chosen, on the lines of the RATP, the SNCF Island-of-France and on networks OPTILE, except for the service roads of airports (Orlybus, Orlyval, Roissybus, Roissyrail and Orlyrail)." There is no mention on RER B line from CDG.

If the Mobilis pass is ok for travel on RER B from CDG to Paris, then it'd be a great value since a single RER B ticket from CDG to Paris costs 8E and a zone 1-5 Mobilis costs 12E. My stay is not long enough to warrant the purchase of a Carte Orange.

But I "think" the Mobilis pass is just for the day. Will you use it enough on your day of arrival for the rest of the money?

Mobilis does not include the RER stretch from CDG.

&quot;Mobilis vous permet de voyager, dans la limite des zones choisies, sur les lignes de la RATP, de la SNCF Ile-de-France et sur les r&eacute;seaux OPTILE, <b>&agrave; l'exception des dessertes d'a&eacute;roports (Orlybus, Orlyval, Roissybus, Roissyrail et Orlyrail)</b>.&quot;
(Roissyrail is the RER leg b/t CDG and Paris)

There is a way to save a few &euro; by using the <i>Mobilis</i> for travel in Zones 1 &amp; 2 and a single ticket from Zone 2 to CDG. Buy a ticket from the airport to La Plaine Stade de France to cover Zones 2-6. It is not necessary to alight from the train (or even ride one that makes that stop).

It is one of the disadvantages of the Mobilis over Carte Orange that it doesn't include airports.

However, you are really worrying about a extremely small amount of money. If you buy a zone 1-2 Mobilis for 5.4 euro for that day's use in the city, and the additional RER fare is 8 euro, that's only 13.4 euro versus 12.1 euro for the zone 1-5 Mobilis. So the difference is only about 1 euro.

If you buy a 2-zone <i>Mobilis</i> for 5.40&euro; and a ticket from CDG to La Plaine for 6.65&euro;, your total is 12.05&euro;, which is <u>less</u> than a 5-zone <i>Mobilis</i> for 12.10&euro;.
