I have jut read on this following website:
http://www.easytravelreport.com/ there will be a Trenitalia strike on 14th June. We were planning on traveling to Siena that Day (staying in Siena that night)
Are ther other options to get from Pisa to Siena (we are considering hiring a car if needed as we want to stop in Lucca also).
Thanks for any advice!!
