The pyramids in Giza/Cairo would be OK. I think the ones in upper Egypt would be way too hot. The new library in Alexandria just opened up and it looks amazing.
I would keep an eye on travel alerts for Egypt. They used to have terrorist attacks mostly confined to the Sinai peninsula. But there have been several in Cairo and Giza. Mostly targeting police. But the church was just bombed and there have been a couple of tourist destinations hit recently too.
Tourism has been all but destroyed since the Arab spring. Expect people to try desperately to get lots of money from you. A 10 pound can ride becomes 200 pounds, for example. I feel badly for them, but the pressure they put on you is huge.
