Anna and Rockoyster , thank you for your reply. Indeed very helpful and answers my questions.
Rockoyster, I will go with your suggestion to get off the bus at Hünibach, Chartreuse. Less walk from bus stop to boat dock and will allow me to stay a little bit longer to enjoy Lake Thun Cruise.
One more question, this is regarding buying tickets with swiss half fare card. I know there are a lot of information in forum threads and online. However, there is still one thing that I still find personally confusing.
I will be in Swiss for 9 days. 3 days in Zurich, 3 in beatenberg, hubel and 3 in Geneva. I will be taking multiple trips on some days and my journey involves to use mix of train, bus, funicular and boat. Initially it seems that swiss travel pass is a better choice (based on online suggestions). However, i decided to think explore other options too, i.e. swiss half fare card.
As I know places I will be travelling during my stay, using sbb.ch site, i try to find cost of travel for each anticipated journey (which will include multiple connections in some cases including changing from train to bus, bus to funicular etc.) then calculated cost of tickets (using half fare card) . Also, considered cost of lake cruises (Lake Zurich, Lake Lucerne, Lake Thun and Lake Brianz etc.).
In my case, it seems that swiss half fare card will be little cheaper than swiss travel pass (for 8 days), however, swiss travel card does not require to buy tickets and hence no need to spend time at ticket windows to buy tickets and in case I change my travel plan, i.e. take different route or change time of travel, i.e. take early or late train/bus, the swiss travel pass will be a good option.
What I want to know is if I buy swiss half fare card (as it will be little cheaper in my case),
(1) Do I have to buy a ticket before each journey from ticket window at train station or bus stop?
(2) Can I buy the tickets online (using swiss half fare card) in advance to save some time?
(3) If my journey (from point A to point B) involves change of transport, i.e. from train to bus, bus to fanicular, bus to boat, can I still buy a single ticket that covers entire journey in advance or do I have to buy separate ticket when mode of transport changes?
(4) What about return ticket, can it be bought when buying ticket for the journey from point A to point B where return ticket will be from point B to point A. In my case the return journey form point B to point A may be through a different route and hence may involve different modes of transport.
(5) Finally, with swiss half fare card, can I buy return ticket from point A to point B that works for whole day and allows to take different route?
Thank you for reading the post with a lots of questions.
