I am having trouble understanding how a Swiss Transfer Ticket works. We will be arriving in Zurich and going directly to Zermatt for a short 4 day ski vacation and then back to Zurich. The Swiss Transfer Ticket sounds like it is the best option, but I don't really understand how it works. Once I purchase the Swiss Transfer Ticket, do you need to book reservations for the dates and specific train. Does a reservation cost an additional amount. With a transfer ticket do I not get a reserved seat? Why would I buy a Swiss Transfer ticket instead of just booking a roundtrip ticket that guarentees my seat on a specific train? Please help!
