I am at my wits end trying to figure out whats the cheapest way to take trains. We are flying into Zurich, staying for a couple of days to get rid of the jet-lag and then traveling to Interlaken (by train). We stay in Interlaken area for 2 days and then need to get to Paris where we will stay for another 5 days.
I am torn between buying a Swiss-France pass and pay for reservations on TGV to get to Paris or buying tickets for Zurich->Interlaken and Interlaken->Paris. I tried to look at the cost and can't figure out all the different reservation fees! Any advice?
