Interesting that you called this itinerary a tour of "North" Italy, cuz half of it is in the central regions.
Day 3: ...當晚在斜塔旁酒店投宿，之後幾日將會以Pisa作基地，去埋Day 4 -7的景點；
-I would suggest homebasing in Firenze instead of Pisa, as it's a better place for eating and enjoying your night times.
Day 6：全日去Cinque Terre...
-Cinque Terre is beautiful! How do you plan to travel between the towns? I highly recommend hiking, but doing all 5 towns in 1 day is too much. So probably best is a mix of hiking, boat, and train.
Day 7：早上去斜塔，預了要排隊上去，所以預鬆d時間...
-book your ticket for the tower in advance to avoid any waits. Also visit the Duomo; 2euros entrance is just too little for such a church!
Day 9：早上在Verona參觀朱麗葉故居，中午起程到威尼斯，晚上在威尼斯訓；
-The Arena is the main attractiong... not Giulietta's balcony!
Day 10：全日在米蘭，目標要購買手信！晚上在米蘭訓；
-keep in mind that everything is closed on Sunday.
