Yeaaaah that's sound good !

In advance welcome to my country ^_ If you like beers, you're going to have a great time (don't forget to go to the Delirium in Bruxelles so you would be able to see Jeanneke-Pis by drinking a nice beer)
Bruxelles is really nice, of course, but it would be sad not to see Bruges when you pass to Belgium. As you were speaking about Italy, Bruges is also named "Small Venise" (La Petite Venise)

In all the case enjoy this nice trip!
