We arrive by air in Florence Sunday morning, 2 May, and depart from Venice Friday afternoon, 14 May. We've seen and loved Florence and Venice, but missed Rome on our only other trip. Our grown kids (22 & 18) are accompanying us this time, and we'll be traveling by train in-country.
We definitely want to see Rome, and I think we have time for one or at most two other stops -- we don't like "drive-by" tourism. Any recommendations that are not too similar to our already-determined destinations, and that don't take us too far off-track? And in what order (the arrival and departure ports aren't ideal but what was available on frequent flyer)?
Thanks for help and insights!
