Subject: Milan and Florence travel time
REALLY you want to drive trough Genova? If you want to go to Genova, you are on your own. Estimate less than 2 hours, but I dislike that road.
>From Genova to Pisa (not very good road until Spezia) consider 1h50, from Pisa to Firenze. Where in Firenze ??? 50 to 1h15 according the place of Firenze where you are going. Anyway from Genova to Firenze, you do not pass from Pisa, getting the route via Massarosa, it is about 2h40 overall Going from Milano to Firenze usually is Via Piacenza-Casalecchio This way is less than 3 hours
