The short answer is Rome, Florence, and Venice form a classic culture route; add Naples, Bologna, or Milan only when the extra move supports your interests and trip length.
Why this question matters
Italy is rich enough that the main planning problem is overloading the route, not finding things to do.
Quick planning answer
For seven days, choose two or three cities. For ten to fourteen days, add one regional detour instead of stacking famous stops.
What to check before booking
- Choose a regional theme
- Allow station-to-hotel time
- Keep at least two nights for major bases
A practical way to decide
1. Start with the part of the trip that is least flexible: the flight, ferry, remote activity, school holiday, or fixed event. 2. Compare the full door-to-door route, including check-in, luggage, walking, waiting, and the final connection. 3. Keep one fallback that protects your sleep, safety, budget, or most important experience.
