Hello Rita_K
I guess you are going to ski and just need an outbound and inbound ticket a few days later? Any further travel planned during your stay? When giving advice, it is always helpful for us to know a bit more about your travel plans.
A group ticket would cost you around CHF 82.60 per adult. A Saver Day Pass would start at CHF 59, if you buy early enough. A full fare ticket would cost you CHF 118.
For the 14 and 8 years old, I would buy the Junior Card for CHF 30 each. It is valid 1 year and the kids travel for free provided one of the adults accompanying the children has a valid ticket. The 14
& 8 years old kids are, even when travelling with the Junior Card, accountable as group members to reach the minimum number of group members required which is 10. The 5 years old does not need a ticket at all (and is not accountable as group member).
So, first, check if you can save 9 Saver Day Passes below CHF 82.60. If not, opt for a group ticket.And buy the two Junior Cards at the ticket desk - there is no better deal.
Does that make sense?
Kind regards,
Roland
