How to Plan a Multi-City Trip

Updated September 20, 2026 · 6 min read
Multi-city trips fail by addition: one more city, one more train, and the itinerary becomes a timetable. The method that works: generate each city's plan separately, connect them with legs under four hours, and enforce the two-night minimum.

All cities must sit on one thread — no doubling back, no legs over four hours. The proven threads: London–Paris–Amsterdam; Prague–Vienna–Budapest; Tokyo–Hakone–Kyoto–Osaka; Paris–Lucerne–Venice–Rome. Every addition must extend the thread, never branch it. One thread, one direction. Legs under four hours. Two-night minimums everywhere.
The Transfer-Day Law
Every transfer is a half-day: schedule nothing on arrival, plan departures after breakfast. The per-city plans should have soft first and last days — that's the stitching that holds.
The Per-City Generation
Generate each city separately at its true length, with its own style and interests. The plans don't need to match — the contrast is the trip's best feature. The cost totals add up leg by leg.

Frequently asked questions
How many cities fit in ten days?
Three, at three-to-four nights each with short legs. Two is comfortable; five is the classic mistake.
Do I need a rail pass?
Point-to-point booked early wins on fixed threads — passes lose.
What's the best multi-city thread?
London–Paris–Amsterdam for ease; Prague–Vienna–Budapest for value; Tokyo–Hakone–Kyoto–Osaka for the classic.
