I traveled with Djed twice -- in 2020 and 2021, and I would travel with them again without hesitation.
Basically, they have a city representative in each major city -- Cairo, Luxor and Aswan -- who meets you at the airport and arranges guides, drivers and whatever other resources you need. My experiences with their guides and drivers have always been superb. I learned a tremendous amount during my trips.
They will send you extensive information about travel details before your trip. The main thing to be aware of early on is that Egypt is a tipping society, and you will need to budget for tips for guides, drivers, the dahabiya crews, ... and basically everything. That's just the way things are in Egypt.
Also, make sure that you are happy with your itinerary because that's what the guides go by while you are there. They will arrange whatever you want to do, and they stick closely to it. If there is something you are on the fence about --- like going inside the Great Pyramid -- just let them know, and they will quote you an optional price for an on-site decision.
A big plus for us was how Djed handled the early days of the Covid shutdown. Our first trip was in March 2020, and, unfortunately the Egyptian government ordered all the airports and hotels to shut down about half way through our trip. We were on the dahabiya, somewhere between Esna and Edfu, when Djed called us to deliver the bad news. Djed told us that we needed to find a flight, any flight, out of the country before the shutdown. After we identified a flight, Djed was willing to take us whatever airport we needed -- Cairo, Luxor, Hurghada, or Sharm El Sheik to catch our flight and get out of the country safely. As we were searching for flights, the guide and the entire dahbiya crew assured us that there was nothing to fear, and that if for some reason we were not able to get out of the country that we were welcome to stay in their homes and with their families for as long as necessary. Eventually, we found a flight from Cairo, and Djed was able to get us from Esna to Cairo in time for our flight. On top of that, Djed gave us a credit for everything we missed in 2020 when we returned to Egypt in 2021. We could not have asked for more professional handling of a very difficult situation.
The only negative is that they can take a long time to respond to email and itinerary requests. When we were planning our original trip, the owner of the company insisted on preparing all the itineraries himself, and the company was getting to size at which that wasn't practical. I think that they have since hired additional people to help create itineraries.
A few random notes from your itinerary:
Giza Pyramids -- If you are the sort of person, like me, who likes to ride every camel and go inside every pyramid, it's a lot to squeeze the Giza Pyramids, Saqqara and Dashur into a single day. On our second trip, we opted to spend a whole day at Saqqara, and I enjoyed it a lot.
The farmhouse lunch, if it's still in the standard itinerary, in Saqqara is a real treat.
I really enjoyed spending the night at Abu Simbel. Not many tours do that, and I enjoyed the Nubian vibe of the little village almost as much I enjoyed the temples.
The dahabiya cruise is amazing. I am looking for an excuse to do it again someday. Bring a swimsuit because you might have an opportunity to swim in the Nile.
Luxor. Think about whether you want to see any of the premium tombs -- Ramses V/VI, Seti, Tutankhamun, or Nefertari --- at the Valley of the Kings/Queens. They are not included with your regular ticket.
Luxor. We enjoyed a felucca dinner cruise, catered by Sofra, so much in 2020 that we wanted to do it again in 2021. Sofra, a restaurant owned by Djed, is seriously good. We ate there several times and always enjoyed it
Have a great trip, and don't hesitate to reach out if you have any questions.
