Hi, we are a family of five with me, my wife, and three children, ages 5 - 9. We are taking a train from Aix-en-Provence to Antibes the last Saturday in May. I've done some research on this but did not realize that my Aix - Marseilles and Marseilles - Antibes rides are on the TER train and not TGV. So with TER, since we cannot reserve seats, I've had some concern about a crowded train and children having to stand for a while (I know they will whine after some amount of time).
Can anyone tell me, rule of thumb, how crowded the TER trains can be in this area on Saturday afternoons? I'm not concerned about the Aix - Marseilles leg. We can get there early to hop on first and it's not a long ride, anyways. There is a 20 minute wait for the connection in Marseilles and it's a longer ride. This is more my concern. There is a Ouigo train for this leg a little earlier in the day so I can reserve this to get seats. It would require us to leave earlier in the day from Aix, and it's more expensive, but I'll do it if it means the difference between standing and sitting. Thank you.
