Pyramids at Giza were awesome except for the persistent peddlers and camels, buffet lunch in Cairo was far better than anything on board ship, The National Museum in Cairo had the entire King Tut exhibit open, but some of the displays were poorly lit, poorly documented and less than professional with hand-written descriptions. Could have done without the obligatory stop at the papyrus store and the jewelry shop where our guide Muhamed probably got a little cut of the action.
Take the train to Rome from the port (cheaper), take the hop-on, hop-off bus tour around Rome. Did not wait in the 2-hour line to go into St. Peter's (been there, done that), be careful, the Coliseum closes at 3:30 this time of the year.
