Thanks for all the wonderful info. It will help us decide if we want to just stroll around or do a tour. We will be sailing a little less than a year from now. We'll have a full day in each port. We did go to Paris on another cruise and did the 3 hour drive. This time we'll pick something else that is interesting by not such a drive. All the people we encountered in Paris clearly didn't like Americans but we found the sites to be wonderful.
