Hi. Trying to get my head around this pass.
I have booked separate seat reservations on both the Eurostar & Interlaken > Lucerne Express for particular dates in August.
I have added these journeys on the Eurail Planner app. Will I need to activate my pass now to save the train bookings for these dates? If I wait to activate, is there a possibility the trains will book out, making my seat reservations useless?
