I've done Venice three times in the Morgan: once from Austria, once from Croatia, and once from Switzerland via Milan. There are too many good places to mention, and in truth I can't remember a few. The road from the Reichenbach Falls to Milan was particularly good, taking in the Sustenpass. It's a cool idea to find a hotel with parking a couple of train stops out of Venice. I've stopped at Mestre a couple of times. Please write how you get on.
