We are planning to stay a few days in Viareggio after leaving Florence in April. We have a tour set up for the Carrara Quarries one morning and would like to visit Cinque Terre and Portofino. We aren't hikers. Just would like to see the different areas and look around a little. Is it possible to see Cinque Terre and Portofino in one day? Maybe ferry around to the different towns? If so, what would be the best way to get there from Viareggio and where should we start? After we leave that area, we will be heading to Milan. Thank you!
