My favorite parts were the Amalfi Coast (of course), the pizza, the gnocchi, the GELATO (white chocolate, stracciatello, dark chocolate, coco, and I know there are other flavors I had), lungomare's, window shopping, walking without having to worry about anything.
Least favorite part: the gypsy's trying to sell you stuff (or force it on you), the smoking! And the train stations :( They can get kinda confusing.
