I would like to know how to go to Paris Metropolitan Area from Paris Beauvais Airport. how much is the travelling fee? and how long does it take to go there? If I arrive very late in the evening 22:00 what would you suggest me to stay one night in Paris Beauvais or strict ahead to Metropolitan Area. Are there any cheap hotel or B&B close to the Beauvais Airport?
The Paris Beauvais airport has a shuttle service that goes to Paris (with the drop-off at the Porte-Maillot - close to the Arc de Triomphe). The shuttle is 10 euros one way, and leaves 20 minutes after each flight has landed. It doesn't say on the airport website ( http://www.aeroportbeauvais.com ) how long the ride takes, but I don't think it is very long. As for accomodation, check out the acc. section here on TP. I've never stayed in Beauvais so I can't give you a heads up on specific places, but maybe someone else can!
If it gives you an idea of time, the airport is about 75-80km out of the centre of Paris, so i'd guess it would take maybe 75mins.
