My wife and I have purchased a 4-country Eurail select pass and will be travelling through Italy, Switzerland and France by train later this month and early next. Obviously there is some debate about whether or not Eurail passes are worth it but we have our reasons for choosing one.
Anyway, my question regards booking seats on the trip from Geneva to Paris. All of the websites I can find say that this is a TGV Lyria route and we will need to reserve seats for an extra fee. However, I can't find anywhere that will let me book these tickets using our Eurail passes. SBB.ch seems to be the most logical choice but after filling in the trip details there does not seem to be an option for Eurail passes in the discount card lists.
The only place I could find to book using a rail pass was the much maligned Raileurope, which was going to cost $84 for the two of us. Seemed a bit much for just a seat reservation - is this really what we'll have to pay, or are they just adding a huge mark up?
Is there somewhere else we can book these tickets online ahead of time? I am a little worried that if we leave it until we are in country (about a week ahead of this particular journey) that all of the passholder seats will have been taken up.
