You should probably just bring the Nikon 17-55mm 1:2.8, and the Tokina 11-16mm 1:2.8.
I find telephoto useful in many situations, so on your trip, personally, I would also bring my Nikon 80-200mm 1:2.8 D. I don't carry the heavy optic at all times. My modus operandi is to scout out telephoto shots in advance and return later with the lens.
I am envious, Dieter. Buon viaggio.
