Hi. I'm thinking of buying a 4 day Swiss pass. There are so many places i want to go from Bern, and I'm thinking of doing 2 or 3 trips per day. But i want to have some flexibility in case, for example, I love the first stop and don't want to do a second trip that same day. Or, perhaps i want to change a trip because of bad weather
So, finally, the question: can i book tickets on the day of travel and then change them if I want to?
Thanks very much Terry
