Find Your Cruise
Very easy to DIY - Try google and 'cruise ports call boards' - the first result will give you all the info under the Europe section. Basically the answer is - go to train station and catch train to Pisa that will take around 15 mins.....
Not a lot ot do in loverno this is the time to take a cruise tour or catch a bus 1e to station then train to pisa 5e but id really suggest take the cruise tour and play safe .
When you get into livorno, go to the tobacconist at where you will purchase your ticket for your bus which you can take directly to pisa or to the train station where you can get the train, for which ever one you choose, you have a walk down to the tower, I did it for the first time this year and did not have any difficulties. A word of warning if you want to go up the tower make sure you make this your first stop as the people are limited and you don't want to run out of time, it is relatively cheap to get there from livorno. Livorno really does not have much going for it, a market and some shops, you could also go to florence by train as well, not done this yet so can not give you any advice. Have a great cruise.
