Have a proper breakfast first. Then go to the Temple of Horus in Edfu. A lot of travelers mention that it is among the best preserved ancient places in Egypt. At the temple, you will find honors for Horus. The god is shown with a falcon head. Look around for the big entry gate. Also note the wall carvings, the tall columns, and the rooms that still look fresh after all these years.
After Edfu, return to the cruise. Keep moving by boat toward Kom Ombo. Eat lunch on board. Then pause for a calm time. Sit back and watch the Nile as the ride continues.
Next, visit the Temple of Kom Ombo. This stop feels different. It relates to Sobek, the crocodile god, as well as Horus the Elder. The plan of the temple is a bit unusual, but it works. The carvings are also easy to spot, so the place leaves an impression.
When you are done, head back to the Blue Shadow. From there, travel on to Aswan as part of your Christmas Nile Cruise Luxor to Aswan.
In the evening, have dinner on board. The night has a festive feel. You will spend Christmas by the Nile, with good food, a warm Egyptian welcome, and local entertainment.
Stay on the ship overnight in Aswan.
