The most common mistake in planning an Italian trip is arithmetic. People count nights, assume a train between cities costs an hour, and end up with an itinerary that looks generous on a spreadsheet and feels like a forced march in reality.
The fix is to count usable days, not nights — and to be honest about what a change of city actually costs.
The rule that fixes most itineraries: every city change costs you roughly half a day. Checkout, transfer to the station, the journey itself, finding the next place, dropping bags. Three cities in seven days is not seven days of Italy — it is about five and a half, spread thin.
What each place actually needs
| Destination | Minimum | Comfortable | What the extra day buys |
|---|---|---|---|
| Rome | 3 days | 4–5 | The Borghese, a neighbourhood you were not scheduled to see, an evening that is not rushed |
| Florence | 2 days | 3 | A day trip to Siena or Lucca |
| Venice | 2 days | 2–3 | The islands, and the early mornings that make Venice worth it |
| Naples | 2 days | 3 | Pompeii or Herculaneum without rushing |
| Amalfi Coast | 2 days | 3 | One day is transit; the second is when you relax |
| Milan | 1 day | 2 | The Last Supper, and the Lakes as a day trip |
| Tuscan countryside | 2 days | 3–4 | The whole point — slowness |
| Sicily | 5 days | 7–10 | It is an island, not a city. Half of it, properly |
Realistic routes
7 days — pick two
Seven days means two bases, not three. The classic pairing is Rome (4) + Florence (3), connected by a 90-minute high-speed train. It gives you two genuinely different cities, one easy transfer, and enough slack that a rainy morning does not wreck the plan.
Alternatives that work equally well: Rome + Naples/Amalfi if you want food and coast over Renaissance art, or Venice + Florence for a slower, smaller-scale first trip.
What does not work in seven days: Rome, Florence, Venice and the Amalfi Coast. That is the itinerary most first-timers draft, and it is four half-days of travel disguised as a holiday.
10 days — three bases, comfortably
Rome (4) + Florence (3) + Venice (3) is the standard ten-day route and it works well. All three connect by direct high-speed rail, the cities are genuinely distinct, and you get one unhurried day in each.
A better version for repeat travellers: Rome (3) + Tuscan countryside (4, with a car) + Florence (3). Slower, less famous, and the part people remember.
14 days — add the south, or slow down
Two weeks gives you a real choice. Either add Naples and the Amalfi Coast to the ten-day route, or keep three bases and spend the extra time actually being somewhere — which, with Italy, is usually the better trade.
If family history is part of the reason you are going, fourteen days is roughly the minimum to add an ancestral town visit without cutting everything else short. That trip is covered in finding your ancestral town.
The travel-day maths people skip
- Arrival day is not a day. A long-haul flight landing at midday gives you an evening, not a day. Plan nothing.
- Departure day is not a day either. An early flight eats the morning and usually the night before.
- So a “7-day trip” is often 5 usable days. Count from that number and the plan improves immediately.
- City transfers cost about half a day each, even on fast trains, once you include the ends.
- Left luggage recovers some of it. Dropping bags at a storage point near the station turns a dead checkout-to-train gap into a real half day.
Rules of thumb that hold up
Two nights minimum, anywhere. One night in a city means arriving tired and leaving before you have seen it.
Base yourself and day-trip. Siena, Lucca and Pisa from Florence; Pompeii and Herculaneum from Naples; the Lakes from Milan. Day trips cost you a few hours; moving hotels costs you half a day and a lot of energy.
Book the high-speed trains, not the regional ones. High-speed fares rise as they fill, so book those ahead. Regional fares are fixed — buy on the day. The full explanation, including the validation rule that fines a lot of tourists, is in our train guide.
Leave one empty morning per city. The best hours of most Italian trips are unplanned, and an itinerary with no slack cannot absorb a strike, a heatwave or a long lunch that turns out to matter.
Before you finalise anything
Three things genuinely need booking ahead and almost nothing else does — the Colosseum, the Vatican and the Borghese in Rome, the Uffizi and the Dome climb in Florence. Those are timed-entry and they do sell out.
Check timed-entry tickets for the big sights
Colosseum, Vatican, Uffizi and more. Compare against each museum’s official site first — direct booking is usually a little cheaper.
