Have been there for a couple of times and people going there with great expectations were disappointed most of the time. But you can consider a Nile Cruise as a good choice. There are boat/hotels sailing on Nile and you are traveling between Luxor and Aswan. Its a good chance to see new places like Valley of the kings, Valley of the Queen and even you can go till Abu Simbel if you want. Have tried one and I can say that it was the best experience for me in Egypt.
