Is there a convenient train from CDG to Chateau-Thierry? We will be meeting some friends next May in C-T and will be taking the train from CGD. This will be on a Sunday, if that makes a difference to the train schedules. I've been trying to search online but all the runs seem to have several transfers. And of course, I can only see schedules out a couple of months, not all the way to May.
Thanks.
