I am planning to travel from Paris to Lucerne in last week of May. We are 2 Adults and 2 kids.
Will stay in Switzerland for 4-5 days to cover Lucerne and then Jungfrach deck.
I was wondering if I buy Swiss family pass, how do I get discount for the travel from Paris to Lucerne for the stretch in the Swiss. I didn't find proper option when I try to make reservation on TGV Lyria train route.
Somewhere else I have read that, through the sncf website discounts are not available and discounts for swiss pass from Paris is available only when we buy tickets in the counters at Paris. But if I don't book in advance, then I believe the cost of ticket will go very high and it will render the swiss pass discount useless for that train.
Can you please advise?
Also can you please advise what would be the best itinerary for 4-5 days. My areas of interest is to cover Lucerne, Murren, Gimmelwald, JungFrau
