How many days do you think would be sufficient in Rome and Florence? We are planning for a trip in May. We aren't the type of people that need to see absolutely everything in a rush, but would rather see less but at a good pace and enjoy the ambiance. We probably want to see some museums but don't want to be inside most of the day, enjoy seeing ruins, enjoy walking and discovering charming cities and love excellent food including wine, cheese and gelato! Right now we have time allotted for either 4.5 days in Rome and 2.5 days in Florence or 3.5 days in Rome and 3.5 days in Florence. Thank you.
