I am planning a two-week trip to Italy the beginning of May with my family (husband and 2 young adults). This is the first time for some of us. We are thinking of taking a tour for the first 9 or 10 days, with 3 days each in Rome, Venice, and Florence; followed by 4 days of renting a car and going south to the Avelino area. Can anyone recommend a reasonably priced tour?

Thanks in advance, Anne, Toronto
