I will be arriving on 18July around 14:30 in Pisa airport and would like to know if its worth to stay overnight then travel the following day to Florence. We have a very tight schedule so we are only interested on visiting the Pisa and the Duomo but not climbing on top. So would like to know if after few hours in Pisa is it alright to travel by train to Florence and stayed there for 2 nights as I learned from other forum there so much to see in Florence compared to Pisa. Any suggestion is highly appreciated. Many Thanks!
