We are taking a trip to italy with our two teenage sons (16 and 18) and are spending three nights there, including the morning that we arrive from our flight, which means we will have two full days plus that first day where you are wandering around half in a daze after the overnight flight. We will also have an extra afternoon/evening when we arrive back before flying home the next day.
I have been to Venice twice as an adult with my wife. However, we were last there in 97, so some of the memories are a little fuzzy. The first time we went we did the typical things - went to St. Marks Square and visited the Basillica and theCampanile (though I am darned if I can remember if we went into the Doge's palace), walked around the Rialto area, etc. The second time we stayed away from all the typical places and instead just walked around on several self guided tours.
Anyway, now that we are bringing our sons, who have never been to Europe before, I do want them to see the "must sees", but I don't feel the need to go heavy on museums and churches - they will get plenty of that in Florence and Rome. So I would love to hear from people about things you saw and did in Vence that you just loved, apart from seeing the most standard sights.
