Another option is to take the TGV, which stops at the TGV-train-station
at the airport (follow the according signs). This extremely fast option (the
journedy takes only 10 minutes) is more expensive during the rush-hour
but can be even cheaper than the RER during the less frequented hours
of the day. All TGV-trains heading into the directon Paris stop at
"Marne-la-Vallée / Chessy Parcs
Disneyland" which is located at the
plaza between the Disneyland Hotel, the Walt Disney Studios and the
Disney Village, next to the bus-station from where the free shuttle bus
takes you to the Disney Hotels with the exception of the Davy Crockett
Ranch, or a short walk takes you right to the entrance of the
themeparks.
