Pisa

Since it was only an hour away by train, we thought we should see the
tower. We seriously got off the train, walked as fast as we could to
the tower (opposite end of town from the train), took pictures, and
hustled back to the train station (more art to see in Florence).

Time spent
Train: 2 hours
Walking: 45 minutes
Gawking at tower: 10 minutes
Trying to get good picture of us holding up the tower: 30 minutes

Pisa seemed nice as we ran through it though.
