One more thing. In Florence on our October 2010 trip, we found out basically after the fact that--at least for us--breakfast isn't the most important thing. At our hotel, breakfast was included, and to cater to American tourists there would be the requisite well-apportioned spread of eggs, bacon, potatoes, etc. That was fine and well, and it was a good idea to have some fuel for a full day of walking & 'touristing'.
But we found out in short order that there's food all over Florence. Between the lampredotto stands, bakeries, the Mercato Centrale for meats & cheeses and the San Lorenzo market with its wonderful fruit, we were still relatively full from breakfast when encountering these magnificent culinary opportunities.
So...for our last couple days on that trip, we only had a roll, coffee & fruit for breakfast, then 'grazed' our way through Florence the rest of the day. Then, at our apartment this last March, we shopped every morning at the Mercato Centrale, picking up prosciutto, salami, sharp Pecorino cheese, rolls, grapes and millefiori (wildflower) honey. That would be our breakfast on subsequent mornings, along with a pot of much-needed American coffee, gotten at the Conad grocery across from the piazza. I love espresso, but after a week of it a regular cup o' joe is a comfort all its own.
After a day of touring, we'd return to the apartment, doze with the windows open, and discuss a late dinner at any number of trattorias within walking distance. Most places don't start serving dinner until 7:00-8:00 PM. It was a glorious, laid-back time, especially during the week when Florence was relatively empty of tourists, at least in March.
Enjoy your planning!
