We three friends are going to visit Switzerland this summer and wanna buy this day pass (all of us are under 25). However, I have 2 questions on purchasing the ticket.
1. Is there a deadline for purchasing this ticket?
2. When I try to add the co-passenger information, the total price becomes to CHF 160. I am wondering upon purchasing, how can I add my friends’ information in the ticket without increasing the price? Or only one of us purchases the ticket is enough (with only my information on the ticket), and we can use this when we travel together later?
Thank you so much for your reply.
