Traveling back thru Munich

So if your flying to the United States just keep in mind you need to eat and buy your soverniors prior to going thru the U.S. check point. I found a ton of great soverniors-german chocolate, shot glasses that look like beer steins. My favorite was a cloth hanging that showed all the cities of Germany-my brothers and I were born in Germany and they loved this gift. Another favorite when we were kids are the Kindereggs; its a hollow chocolate egg with a toy in the middle; I always make sure to grab some of these when I'm in Germany-a family favorite.

Pisa Bound

This week I'm traveling to Pisa, Italy.
5 connecting flights starting Sunday with arrival Monday.
Starting in Colorado Springs to Houston to Newark to Munich to Pisa.

Going to Pisa for business but I should have some time to visit the sites.
Anyone have suggestions on what to see and some useful Italian phrases?
