If you are in Luxor, I'd recommend Mustafa (full name Mustafa Boghdady Ahmed Abdallah). We met Mustafa outside our hotel... he took us to the temple of Karnak at sunrise, then drove us to Abydos and Dendera. Full day pack at a reasonable cost. That was our last day in Luxor. The following day, he was on time to take us to the airport. +20 10 92932238 better to leave him a voicemail as he speaks 6 languages but not formal education; writing is not his strength. Mustafa your trustworthy driver in Luxor!
