We will be visiting Porto Venere on the Crystal Serenity on April 29, 2014, and we would like to spend our day at the Cinque Terre. We will have time to visit only three villages. In the past (and I expect again in the future), Crystal has offered an excursion that begins in Manarola and includes a 25-minute walk to Riomaggiore followed with a ferry to Vernazza. Alternatively, my travel agent is offering us a private tour that includes visits to Riomaggiore, Vernazza and Corniglia - spending an hour to 90 minutes in each town. It has not yet been clarified, but I do not think that this private tour includes a coastal walk from one town to another, and instead, the private driver transports us from town to town by car (unless, of course, we design our tour to include a coastal walk.) I should include that we are good walkers, but we are not fans of hiking or climbing uphill and downhill. That being said, what is your experience at the Cinque Terre? What are your favorite villages? Which is best - the Manarola/Riomagiore/Vernazza combination expectedly offered by Crystal, or the Riomaggiore/Vernazza/Corniglia combination offered privately? Or, on the other hand, is there another village not listed that is a "must see?" Since the tour offered by my travel agent is completely private, I can design it however I want, and we can create our own combination of villages and/or walks. Please share your Cinque Terre experiences and recommendations.
