Hello,
We have a group of Four adults that will be traveling in France from Paris to Grenoble, and after staying there for three days we then travel from Grenoble to Lauterbrunnen Switzerland and spending 5 days in that area sightseeing, and finally back from Lauterbrunnen to Paris. Can anyone recommend best rail pass for this itinerary? Single tickets in France and a Swiss Pass for Switzerland? Or better to rent a car for the entire trip? Thanks!
