If you are seriously interested in Egyptology there are of course interesting sites along the way but driving through Middle Egypt can be problematic for tourists and you may require police permission and/or escort to visit them. Cruises between Luxor an Cairo are few and far between these days, they take 10 days or so and are expensive. I would fly.
Thanks again... great advice :)
Your quite welcome and thanks . Have a great trip.

Hi. I traveled by plane - it was quick and the price is not bad if you book way in advance.
