Hi, my mom and I will be in Europe in early October and will be spending our first 4 nights in Mürren. We fly into Zurich and arrive very early in the morning, will catch an early train to Mürren, spend 4 nights there, and then take the train to Milan. From what I can tell from all my research, our best option would be to buy both the Berner Oberland Pass and the Half Fare Card. I'm thinking of getting the BO Pass for 4 days (there is no option for 5), having it start the day we arrive, and then just purchasing a point-to-point ticket to Milan on the day we depart. Does that make sense? Or should I just get it for the 3 days we are in the area all day? Or splurge for 6 days and have one wasted day?
Also, on the SBB app, I have seen something called a "Saver Day Pass." Am I allowed to buy that pass, and does it include any and all travel that day or only the train ride that shows it? Also, are the prices I am seeing already assuming a Half Fare Card, or are those the full prices (so I will only have to pay half)? For example for Zurich Bahnhof to Mürren BLM, the point-to-point ticket is CHF 92.80 and the Saver Day Pass price is CHF 52. Can I do the Saver Day Pass, and with the Half Fare Card, would it be even less?
Additionally, when looking on the site for the Half Fare Card, they give me the option of a "Special Price Half Fare Travelcard" for 165 rather than the typical 185. Am I eligible for that? And once I purchase both passes (Half Fare and BO), will they show up on the SBB app? Also, since my mother is older, can I do all the passes and tickets for both of us in my app?
Thanks for any guidance you can provide! It's all a bit confusing to me! :)
