We wanted to travel to Disneyland on the 10th of August (Saturday)
However the website states that
'From Saturday August 10 to Sunday August 18 (inclusive) RER A trains are not running at all, all day.'
So I was wondering whats the best option of travelling to Disneyland and back on this particular day?
Using Metro Line 1 from Paris to Chateau de Vincennes. Then walk to Vincennes RER station and take RER A from there to Marne la Vallée station (Disneyland). The rail closure doesn't affect RER A train at or after Vincennes station.
Using a day ticket such as Navigo Jour, Ticket Mobilis, Paris Visite would make the transfer ticketing easy (use the same ticket for transfers / return trip).
