It looks like most people fly into and out of Milan. Has anyone stayed in Milan for several days or more? This coming October we have an unexpected 4 days between our stay in Rome and needing to be in Paris. We like walking, museums, theater and music (yes, MIlan has La Scala!) Is there enough to keep us busy for 4 days? We will not have a car, but are comfortable with public transportation for days trips. In past years we have been to Florence and Sienna, so no need to return to either. Our plan would be to take the train from Rome to Milan, then train again to Paris.
