We will be travelling to Switzerland, 2 adults and 2 children for a week holiday and will purchase the Half Fare Swiss Card. One of the children is my son, so my understanding is that we will get the Swiss Family Card with the purchase of Half Fare Swiss Card. The other child is my nephew, aged 14. Is it best to purchase a children’s co travelcard for him? Can this be purchased online or only issued at the ticket station? I read that it can take 10 days to be issued but for tourists can it be issued immediately at Zurich airport station?
