Where can I find what is open/ close for August? We planned our trip on 14-18.08, I've red your suggestions what to see and do, but have a problem with checking what is open in terms of sightseeing and eating .
Other question: palio in Siena. Is it worthy to lose one day in Florence to go and see palio? I'm scared of crowd. And how to go? Some days ago I've checked the buses and to Siena was OK, but I couldn't find a bus after, let say 9 p.m.

Any suggestions?
