Seeing more than one country in a single trip is wonderful — if you plan it properly.
Fewer stops, longer stays
A common mistake is to try to fit too much in. Two or three nights in each place is often too short; consider spending more time in fewer places.
Use rail where it makes sense
In much of Europe, trains link city centres directly and can be a pleasure in themselves.
Mix cities with quieter places
Pair a busy city with a lake, a village or a stretch of coast so that you can recover between highlights.
Check entry rules early
Entry and visa requirements for travel across multiple countries depend on your nationality and plans. Always check official sources for the countries on your route.
Let someone else coordinate
Flights, trains, hotels and transfers across borders involve many moving parts. A single coordinator can save a lot of stress.
