Hi, I am staying at Jungfrau region for 5 days 4 nights. I am planning to buy 4 days JungFrau Travel pass with a reduced price using Swiss Travel Pass Flex 8 days (STP).
I am planning to activate Swiss Flex Travel pass on 24 to 26 Sept and 01 Oct onward.
1) When i activate Jungfrau travel pass for 4 days (27 sept to 30 Sept) usage, does these 4 days need to also present/activate Swiss travel flex pass?
2) Or i just need to activate the swiss flex travel pass on the day when I purchase jungfrau travel pass (e.g. 24 sept)?
Thanks for taking time to ask my questions!
