I'm having trouble deciding what to pack for a month-long trip in Egypt. I haven't worked out the itinerary yet but am leaving in a few days already because I'll be in Turkey before Egypt. I'll probably end up going all over the place from Aswan to Red Sea destinations to Cairo and Alexandria. Should I prepare more for warm weather or cooler? Besides clothing items, what are some must-pack items, kind of things that a typical American wouldn't want to be without while in Egypt?
