I admit it. I'm a travel-virgin. But I've always wanted to see Italy (Rome, Florence, Tuscany, Pisa). My husband and I have decided we're going to take the plunge and go this year. What's the best time to go? Is a tour group the best way to go for a first-timer? (if so, which one?). Is there one location that we could stay (as a base camp) and go out daily from there to see all the sites? Any help, suggestions, wise words would be appreciated.
