free tour with armed guard??
besides, I'm not sure that will help, I'll be flying into Cairo and then originating another trip from there
I'll be on my way to a honeymoon.
Other than the Pyramids, check out the Egyptian museum. One can spend days in there! It's right by Tahrir Square.
Also to see is the Ben Ezra Synagogue in Old Cairo. (

Now that you mention that you are hoping on another flight in Cairo, if your layover is only a few hours, I wouldn't recommend going into town, as during the day the traffic can be horrendous. (Although, last time I was there, I arrived very early in the morning, and my taxi driver jetted into town, and flew through every red light without braking! ) I guess they only stop at green lights for the other professional Egyptian taxi drivers.
