I loved my trip to Egypt 3 years ago, then there was tension too, mostly riots in bread lines, and at gas stations, nothing I was going to be doing. Arranged a car to pick me up at the airport through the hotel, and stayed at the Le Meridian Pyramids, and always arranged a car through them. Just be more alert than most places, and watch your surroundings. I do recommend the Le Meridian, great views, I had a room with a view of the Pyramids. It is on a noisy street though.
