We will be in Florence in late November and do not know what to expect beyond what books note. Any suggestions? In 7 days, what are MUSTs to see? My travel partner has a bad knee and cant walk long distances, any suggestions for seeing the sights? How is weather? Lines? My last time to Italy was a few years ago in August, which was too packed with tourists, which I dont expect in Nov. Also looking for unique events and suggestions for the over 50.
