Arno: "...but prices won't change until next year..."
I must say with all due respect to Arno (I am post 1 and Arno is post 10044), it's not entirely true that the price remains the same ... The SBB rates may be fixed for a year, but SBB offer "saver" discounted tickets that are super "early bird" discounted: Quoted off the SBB link I provide:
"...It’s fun to travel so cheaply by train! With the new Saver Day Pass you can travel in the whole of Switzerland for a day on all routes in the GA area from as little as CHF 29 with a Half-Fare travelcard and from CHF 52 without a Half-Fare travelcard... "
Click the "Purchase Online" button so that you can see availability for your dates.
From what I have observed, most often the price (with HFC, which you have) jumps from CHF 29 to CHF 39 between 30 days and 29 days before the travel day, then it goes up even more the less the lead time! So you would have to go onto the site and buy each day you want, early on the day of 30 days before each of those days, as the price could even change in the day.
