Hi, I'll be going to Disneyland on the 17th of July. I noticed that the RER A from Disneyland back to Paris stops running at 9pm on weekdays for summer maintenance. What would be the alternate route to go back to Paris after 9pm?
Take the RER A from Marne la Vallée / Disneyland to Vincennes RER station, exit the station, walk to Chateau de Vincennes Metro and take Metro line 1 into central Paris. You'll need both a RER ticket for Marne la Vallee to Chateau de Vincennes on RER and a Paris Metro ticket for Chateau de Vincennes Metro to Paris to complete this transfer.
