It is about 45 minutes from Ramses to Airport.
It is about 1 hour from Ramses to pyramids even though you can seem them in the distance.
Cairo traffic is terrible beyond description.
I had the Ramses door man negotiate a driver to take us there, wait there while we were at the laser light show and bring us back and put it on the hotel invoice.
The Ramses staff treated my wife and I royally, and I would stay there exclusively.
