Thanks for all the comments about what we should try to tackle in 7 days. From a purely uninformed perspective, Venice seems to have more to do than Florence proper (the area around Florence seems very robust, though). It just feels a little wrong to go to Italy for the first time and not go to Venice. What if we just did Venice and Rome? Is this conceivable in 7 days without losing my gourd? I don't mind moving around when I travel.
