We have our hostels booked and our trains to and from Florence, but I have a few questions about Siena:
1) Is it easier to get the bus or train to Siena from Florence and back again? Do we have to book in advance for this?
2) Any suggestions about what to do in Siena? We want to see the Palazzo Pubblico and the Cathedral - do we have to book in advance for these? Any other suggestions for places to visit or eat also welcome :)
