Hi, we're flying into cdg, arriving at 8:10 am, then need to catch a tgv down to Arles by that afternoon to board a barge. There is a train at 10 and another at noon. I've read all through previous posts that it can take up to 3 hours to catch a train after landing, so I did go ahead and book the one at noon.
If we do make it through faster though, won't I be able to exchange my ticket for the earlier train if there's room? I shelled out some extra $ for the Tgv Pro Second ticket, which states that it is returnable and exchangeable up to 2 hours after departure.
That sounds pretty clear to me but I'm unsure because all the posts I read keep saying not to book ahead because if you miss your train you're completely out of luck. Are people just referring to the cheapest, non exchangeable tickets, or am I missing something here? Thanks in advance for your insight.
