Begin with the decisions that shape everything else
The most useful early choices are trip length, season and arrival city. Those three decisions determine how many bases make sense, whether trains or flights work better and how hard the trip will feel once you land.
A one-week trip usually needs fewer moves and more discipline. Two weeks offers more freedom, but only if you resist turning every possible city into a stop.
Choose a route that respects geography
Europe can tempt travellers into treating short flight times as proof that every idea belongs in one itinerary. In reality, airport transfers, station changes, hotel check-ins and fatigue can steal more time than the map suggests.
Routes feel stronger when they follow clear corridors, such as one country, one region or one set of easy rail links.
Book the anchors and keep the rest flexible
Flights, the most important stays and high-demand transport segments are often enough to lock in the shape of the trip. After that, a little breathing room gives you space for neighbourhood wandering, weather shifts and recommendations you pick up on the road.
