I realize I'm late to the game, but I've been busy.
I haven't been "galavanting" through the Middle East per se, but I have traveled through a little bit of it. Unfortunately for you, most of my travel was in Saudi Arabia. If you ever get the chance to tour the west coast of Saudi Arabia, it is amazing.
Otherwise, I think Sharm El-Sheikh and some places in Jordan will probably have to suffice. I believe there are some Nabatean tombs carved into the rock in Jordan.
In Egypt, I agree with most of the comments about Cairo. The key takeaway for me was the sheer mass of humanity. Apart from the Pyramids, the key places I remember were The Citadel, The Nile (obviously) and some sort of museum of antiquities (I've forgotten the name).
If you can do it, I highly recommend a trip to Luxor. You can visit Karnak Temple and the Valley of the Kings. This will be well worthwhile. I wish we could have made it to Aswan Dam, Abu Simbel, etc., but I guess I'll just have to make due with the pictures in the History books.
