I know Sunday June 10 was not previously listed as a strike day. Are the SNCF train RER C running from central Paris to Versailles? I am trying to make plans to get to Versailles on Sunday. I have my tickets to Versailles. I need a train ticket. I went on the SNCF site and it shows no tickets available. Not sure if that means not running or sold out. If can't get train ticket how do i get there? My tour is at 9:30am for the Kings Apartments.
