Skip Pisa ... its a dump and (leveled in WWII, town looks like Brooklyn with its 1950's style track apartments). Goto Florence instead, most beautiful city I have ever seen.
Thanks for the info. We're just taking a day in Pisa to de-jetlag; the logistics work well. See the tower and the basilica, yadda, yadda. I'll be in such a fog that it won't matter! I've been to Florence twice and agree with you, but I'd rather go in the spring or fall when you can actually see something besides the back of other tourists' heads.
