I'm trying to plan an itinerary for a late September 2024 trip and have been looking at SNCF connect to get an idea of train schedules. As it's too soon to book for September I've been looking at dates in mid-late March to get an idea of how many trains run on particular days, what times etc. Does anyone know how likely it is that what I'm seeing for March will bear any resemblance to what actual September schedules look like?
If it matters, I'm fairly sure we're going to visit Paris, the Loire Valley, and Burgundy, just not sure yet in what order. So I've been looking at Paris to Tours (or Saint-Pierre-des-Corps), Tours to Dijon, Paris to Dijon, and vice-versa for all of those.
