I'm planning a trip to Italy and was thinking about going to Portofino and Cinque Terre end of January. I noticed that a couple of the hotels that I'm looking into are closed from Jan-Mar. Is that because of the weather condition? Just wondering if its too cold to visit at this time of the year and if all the restaurants and shops are going to be open? We don't mind if it's a little cold as long as it's not unbearable. We are also looking to hike some of the trails in Cinque Terre. Are the roads going to be closed? We are planning to rent a car and drive from Milan.
