We are a 70ish couple in good health and seasoned travelers. We are planning to spend a few days in the Lake Como / Lugano area and will try to visit both places. We will be arriving by train from Milan and will not have a car. I am looking for suggestions about which of these places, Como or Lugano, would make the best base for seeing the area. We have traveled a lot in both Italy and Switzerland but have never been to this area in either country. Any suggestions?
