I am looking at the Classic Italy CruiseTour. It seems to add $3140 pp to the overall cruise cost. I tried to come up with the cost of doing the same itinerary on my own and come up much cheaper than that, and think I was being generous in my estimates. Does a European cruise tour include air? I don't see anything that would indicate that it does, but that is the only way booking this through Princess seems like a good idea.
