re: Italy trip average costs

Average cost of what? Where?

This is going to vary wildly based on you. Where are you going? Different Italian regions and cities will cost different amounts.

What level of hotel do you want to stay in? Airbnbs?

What level of restaurant are we talking? Street Food or Michelin Star? Moderately priced? Casual?

Are you taking trains? Cars?

So its a lot of questions. Also time of year matters.

In Rome, you can easily get away with 100-150 a night on hotels and be fine. In Venice, accomodations are much more expensive, think 175-250.

In Rome and Florence, you can eat street food or paninis during the day and probably spend 10 euros a person.

If you're going to Amalfi Coast, accommodations are much more expensive, and eating out well can be as well. Places like Positano are outrageously expensive.

If you want to go to the country side in Tuscany, you can find pretty good deals on Airbnbs or Agriturismos.

The longer the train ride, the higher price it will be. A train ride from Rome to Florence will range in price from 9.90 Euros to 18-21 euros.

So its going to vary wildly.
