He firenz and welcome to the board! A bunch of us on the board did your same itinerary awhile back. We really enjoyed the Pompeii visit! If you don't want a long day trip to Florence, you might want to consider the leaning tower of Pisa, instead. We really liked that tour as well.
I did a search for you to find all our old posts about the cruise but the search pulled up a bunch of odd posts instead, lol. If you see any old posts with 007 in the titles, that was the name we gave to the cruise.
