I have another question about train travel - some friends of mine are having some difficulty so I said I would help them out. They are an older couple - mid 70's - but very active. They are taking the Queen Mary to England (from NY), then will go to Edinburgh, Sweden, and then France. They are staying in Blois and have rented bikes to travel around there.
Here's where I (they) need help. I'm familiar with other European train systems but haven't ridden a train in France in over 20 years. They want to take the train from Blois to Arnhem on a Sunday morning (October 2nd). I've been checking schedules on sncf-connect, nsinternational and bahn.de and have a general idea of how they need to get there from Paris, but I'm not sure about getting them from Blois to Paris.
I'm assuming they should book the ticket from Paris to Arnhem ahead of time. I found a Thalys train leaving Paris Nord at 12:25 pm and arriving at Arnhem Cental (via Schipol IC) at 16:44 (I also noticed that the ticket was about €20 cheaper on the Netherlands site).
But what about getting from Blois to Paris? I'm assuming it is a regional train so probably no need to book ahead but wanted some confirmation about that. Is it better to book ahead or buy a ticket at the station while they're there? It looks like they will have to transfer once they get there to Nord, so I want to make sure they have enough time. They will have one carry on roller bag each and a personal item, so they are not overladen. They are also somewhat experienced travelers but dealing with booking trains online is more difficult for them.
Thanks for any help you can give me!
