My wife and I are in the preliminary stages of planning a trip to Europe (probably 2019 at this stage, but possibly earlier). When I was a kid, my parents took us to Europe in the late 70s, and we used Eurail passes to get around everywhere.
I recall this gave us a pretty flexible way to travel the continent back then. Is this still a good way to travel around Europe? Or are we better off buying rail (or air) journeys separately in advance?
Any gotchas/tips also appreciated.
