Travelling to France next month with partner and 3 kids. We want to travel by train so I've read a bit on seat61 that it's best to book point to point tickets 2-3 months in advance but since we're past that now would it be better to just get a a eurail pass? I have seen a lot of people say a pass isn’t worth it and can be a hassle to use as we still need to pay additional reservation fees on the high speed trains and it doesn’t cover the ouigo train which we will be taking from paris to marseille and avignon to paris. Here are the other trains we will be taking:
marseille-carcassonne
carcassonne-avignon
And possibly these ones for a day trip:
paris-nantes
paris-lille
marseille-nice
carcassonne-bordeaux
carcassonne-toulouse
carcassonne-alet les bains
avignon-st etienne
avignon-lyon
avignon-aigues mortes
avignon-cavaillon
