I've read half and half --bus is better/train is better. They seem to be about the same length of travel time but I know you have to get a ride into Siena from the train station and there is a train change but not a bus change. What do you think?
My second question is, no matter which mode of transp. we use, how do we get tickets--buy at the station that morning, find a TA in Rome, find a train or bus ticket office in central Rome? I don't want to have to use up precious time to go out to the station the day before to buy them.
Thanks
