Before we decide to go to CT. I am concern about the timetable train. Do you know what's time the last stop from CT to Pisa and Pisa to Florence after we go to CT?
Looks like there is a 9:07 pm train from Monterosso to Pisa (arrives 10:17) and then departs Pisa at 10:30 and arrives in Florence at 11:50.
I'm not sure we're understanding the question: you don't want to go from the CT to Pisa late at night if you're going on to Florence that same evening? Not if you're intending to sightsee in Pisa, anyway.
FSg You could answer the question yourself by looking on the trenitalia website.
