Wife and I are active seniors thinking of Florence in late September. We like things of beauty but don't want to spend all day every day in museums.When we went to Venice we did museums, churches etc in the mornings and then went on a waterbus trip to one of the islands for the afternoon. (We enjoyed the sitting down looking at the views.) How do we plan Florence and surrounds? Trains, buses and boats are fine. hat must we see? Where best to stay?
