I've been going over my options and filling out the spreadsheet that is out there to calculate everything, and I'm pretty sure I will get the 8 day STP for me and my son (daughter will be free with family pass). But, I'm a little confused on which legs of my travel are only covered 50% vs. 100%. I'm staying in Wengen and I see mostly dotted lines around Wengen. These are my plans. Does anyone know for sure if any of these legs are only 50% off? Or do I need to break them down further b/c part of the leg is 50% and the other 100%? I want to get my spreadsheet as accurate as possible so I can budget how much additional $ I will need for the trains.
Day 1 - Zurich Airport - Wengen
Day 2 - Wengen to Grindelwald
Day 2 - Grindelwald to Wengen (return)
Day 3 - Wengen - Shilthorn
Day 3 - Schiltorn to Murren
Day 3 - Murren to Lauterbrunnen
Day 3 - Lauterburnnen to Wengen (return)
Day 4 - Wengen - Interlaken
Day 4 - Interlaken to Thun (boat)
Day 4 - Thun to Interlaken (boat return)
Day 4 - Interlaken to Wengen
Day 5 - Wengen to Lucerne Golden Pass (round trip)
Day 6 - Wengen to Zurich
Also, I originally thought it wouldn't be worth it to get the 8 day STP since we really only have 4 full days of travel and then 2 days would just be travel to/from the airport. But if I'm figuring correctly, the 4 day passes would come to 517CHF for me and my son. And then if we paid the fare to/from Zurich airport, it would be 612CHF round trip for 3 of us? And the 8 day STP for me and my son would total 771CHF (254 more than the 4 day). So obviously, it would make sense to get the 8 day pass if I'm doing the math correctly. Can anyone confirm?
Thanks for the help!
