Last week , VEA (http://www.vea-shuttle.co.uk/) has open a new road by bus.
For 140 kilometers it costs 25 euros per adult
There is 3 deprture from Beauvais at 10h00, 15h00 and 20h30.
I think it's a good news for Beuavais Tille Airport, because it was impossible te reach Disneyland easily.
Therefore it's semms that the bus is stopping in CDG Roissy Airport and You can use it to reach CDG for only 20 euros.
I think reservations on website are necessary ?
