We're going to Bayeux for the day from Paris. I've printed tickets at home for the majority of the trip (Paris-Caen & Bayeux-Paris). Once I get to St. Lazare, what do I do with these "home printed" tickets? Are these my final tickets or do I need to exchange them at a window? I know there are turnstiles on the RER/Metro, but I believe there are some kind of "stamp machines" you need to put these in here? How do these work? We have assigned seats- will getting on the correct car number/seat be obvious? Will we need the tickets again- show on train, to exit? Is there a sign by each train at St. Lazare, or just a main board with track numbers- will this be at all confusing?
OK, now I also have to buy tickets in Paris for the short regional train trip from Caen to Bayeux. I was told I can do this ahead of time so I'll buy them a few days before. How do I ask for this exactly (speak very little French)- just show them the stations; Caen/Bayeux? What do we do with this ticket in Caen- does it work with turnstiles, stamp machines, what? We have to make this connection, so what does this station look like, will it be obvious what to do when we get there?
I'm assuming Bayeux will be the same as St. Lazare since we have a home printed ticket all the way back to Paris (no connection this time)?
I know I'm obsessing over the details, but it's going to be a very early morning, I've never done an of this before, and I'd hate to miss our train/connections...it would be a very expensive mistake for our large group.
Thanks so much!
