Looking at buying a 5 or 7 day pass now and using in March 2025. We fly into Zurich mid month and plan to train it to Interlaken. Then on to Strasbourg, Belgium and Amsterdam. Those trips I want to book close to the day as they will be at the mercy of flights. However I want to book the train from Amsterdam to London as early as possible as we will be flying out of London in the evening of our train to London.
Can I buy now, activate for March and book our last train at the end of March now?
