And to complete on previous post, how to get from CDG airport to Paris :
- CDG airport -> Gare du nord with RER B (this a kind of subway, line is in blue on maps)
- Gare du nord -> Haussman-St lazarre with RER E (pink line on maps) u can check www.ratp.fr
to get sched of those two.
- There is a bit of walk in St-lazarre (5-10min), follow the signs that say "SNCF grandes lignes"
- St-lazarre -> Trouville-Deauville by train (andrews link is good for this). U might need to change at lisieux, which is very small station. Attention, last train is at 19:10 so you shouldn't land at CDG after 17-17:30 max.
