Looking through the forum, I'm glad I'm not the only one very confused about our travel pass options :)
I will read some of the other posts, but my simple question/clarification is if I need to get both a Travel Pass/Card AND a Regional Pass? Or is it one or the other? Most of our time will be in Bernese Oberland, so I want to be able to use the lifts/cable cars/gondolas most cost efficiently, and I know we'll also do Schilthorn one of the days. Rest of our time isn't planned out exactly yet, I'm not sure if I'll ever have it 100% set in stone, so I figured there might be some unplanned use of some lifts/cable cars while in BO, so I guess I'm open to paying for some convenience?
Day 1 - Arrive at ZUR airport, go direct to Murren.
Day 2 - Murren
Day 3 - Murren
Day 4 - Murren --> Lucerne (potentially explore Interlaken briefly)
Day 5 - Lucerne
Day 6 - Lucerne --> ZUR in the morning to catch our 10:30 flight
Thanks for your time!
