Hello.
We are traveling via train from Marseille Saint Charles station (since we are staying in Vieux port area) to Arles for the day, then on to Avignon. I am using the sncf-connect site to review train schedules
There is a Zou! that takes ~ 1:05hr leaving at 8:40 AM from Marseille -> Arles. Do I need to buy in Advance?
On our way from Arles-> Avignon Centre there are a few good options. "Direct Zou!" vs "Direct TGV inoui" vs Direct TER. Are any of these things I need to book ahead? Second 2 options seem to have 1st vs 2nd class ticket options. We are traveling on a Wed in October.
