We just returned (2 weeks ago) from a 2 week trip to Egypt. We spent 2 nights in Alexandria, and its probably safer than your home town. The only thing is that I don't think its a great port, since other than the library and the Catacombs its not a great tourist destination. I know that the cruises will sometimes run an excursion to Cairo, but keep in mind that its more than 3 hours drive each direction.
