What counts as a 'short trip'?

Trips under 5-7 days or involving fewer than 3 major train journeys.

Is the 4-day Eurail Pass a good deal?

Only if you take 4 very long, expensive trains. For short hops, individual tickets are cheaper.

No, Eurail never covers local city transport.

Eurail is rarely worth it for short trips. If your itinerary includes only two or three nearby cities, individual tickets are usually cheaper.

High daily cost: A Eurail pass can cost €50-70 per travel day. A short ticket from Florence to Rome might only be €25 if booked early.
Advance booking: Short trips usually mean fixed dates, allowing you to grab "Super Economy" fares.
Guaranteed seating: Individual tickets include your seat. Eurail often requires an extra step (and fee) to reserve.
