This was a terrific introduction to the Grand Canal and the areas not too far from St Mark's Square. We had two female guides, both terrific -- knowledgable and energetic. I would recommend this tour, at least with these guides!
For me the most exciting thing was the views of the flower fields from the bus. The gardens, though exquisite, are crowded, so it's a special pleasure to see the ribbons of color going by from the bus. If the drivers could keep this in mind it would be helpful!
