Are regional trains reliable?

Yes, but they are slower and stop more frequently. Expect minor delays, so don't book tight international flight connections on the same day you travel by train.

Can I use a credit card everywhere?

In major cities, yes. However, keep at least 50 Euros in cash for small bakeries, independent coffee bars, or rural shops that may have a minimum purchase requirement for cards.

How to travel Italy on a budget as a couple

Travel Italy as a couple for $160 per day by staying in Agriturismos, taking regional trains instead of high-speed ones, and eating one meal a day at a grocery store or bakery. Prioritize the off-season months of November or February to cut accommodation costs by up to 40%.

Use regional trains (Regionale). Avoid Frecciarossa or Italo high-speed trains. Use the Trenitalia 'Regionale' trains. They take longer, but a trip from Florence to Rome costs $20 instead of $50 per person if booked last minute.
Dine like a local to save. Eat a 'colazione' of coffee and pastry at the bar counter ($3 total) instead of sitting at a table. Buy fresh bread, local cheese, and prosciutto from a 'alimentari' shop for lunch to picnic in a piazza.
Choose smaller cities over hubs. Base yourself in cities like Bologna, Perugia, or Verona instead of Rome, Venice, or Florence. You get the same Italian experience for 30% less in daily costs.
Get an Aperitivo. Between 6 PM and 8 PM, order an Aperol Spritz ($6-$8). Most bars serve an extensive spread of finger foods, pasta, and snacks alongside the drink, which can serve as a light dinner.
