Such good news as from yesterday the convoy system ceased around Luxor. This means you do not have to leave at a set time, travel at breakneck speed with no stops, visit the sites at the same time as 100's of other people or only have a short time.
For sites like Abydos this will mean lots of time and an opportunity to visit the entire site and no compulsory visit to Dendera.
For Aswan instead of just being able to visit Edfu and Kom Ombo on route you will also be able to stop at Tod, Moalla, Esna, Gebel Silsila and El Kab
I understand the Aswan to Abu Simbel convoy still operates but who knows that might change as well
