I am just starting to gather information about vacationing in Italy with my family. Kids will be 11 and 13 when we go and we will have 2 weeks to be there. I have bought travel books and read websites, but can't seem to find one major point. How long do you recommend to stay in one place in order to see all the famous sites? Two days, four days, a week? We are looking at starting in Naples and going to Rome, Tuscany and Venice.

Any recommendations? Thanks so much
