This is DoRae....I'm having trouble figuring out some rail times etc. I have purchased 2 Eurail Passes and have 1st class reservations on 3 TGV trains; however, originally we planned to go to Geneva from Nice via TGV and then to Chamonix but they cancelled the Nice-Geneva TGV so....they suggested going to Valence via TGV and then taking other trains to Chamonix....only trouble is how?.....via Lyon? via Grenoble/Chamberey? I'm so confused about this part. Our TGV train gets to Valence at 2:14 on June 9th.....Has anyone gone to Chamonix this way? Do you have any suggestions? Do I need tickets ahead of time or just hop on those trains with my rail pass? Thanks for any help you can give me. I really like these forums....talking to REAL people who have "been there, done that"!!
