So now I'm leaning more towards a "grand tour". I figured I could engage the hive mind that could tell me anything I can skip or that I'm missing that's just "must see". Interested in anything with Gothic, Renaissance, and especially Baroque art and architecture.
Things intentionally not on the list - UK ( seen it ), Ireland ( separate trip ), Paris ( seen it lots - love that city ).
I'm planning on traveling mostly by rail, with the occasional ferry. Some places were chosen simply because the train ride between them is supposed to be especially scenic.
Anyway, without any more ado...
