Can you go to two countries in one travel day? And suggestions for Berlin to London and back route. First time Interrail user!1. I want to travel to the UK from Germany (where I live), and my intention is to travel to Brussels, then to London (via the Eurostar) on the same day - or does the Eurostar count as one travel day on its own?2. And also, can I take any route from Berlin to Brussels? IE, could I go from Berlin to Dortmund, stay there for a few hours, then go from Dortmund to Cologne, Cologne to Brussels, or must I take the most direct route?3. And finally (sorry for all the questions!), I was thinking of going to Brussels one way, and to Amsterdam or Paris on the way back from London via the Eurostar - any suggestions for best route?I’m trying to plan the quickest/cheapest but most fun way to go back to the UK, and deciding on whether to book the Interrail or individual tickets!Thanks in advance!!
