Wife and I are going to go on a Egypt trip early 2023. We've never been on an actual tour before, we've always traveled by ourselves, but on this trip we'll have a guide for part of the time in Cairo and then will have a free day to do other activities.

Planned activities as part of tour:
• Visit the 3 Great Pyramids (Cheops, Chefren and Macarinos).
• Visit the Queens Pyramids (availability to enter to one of the queens Pyramids
• Visit the Great Sphinx, which has kept its secrets for centuries.
• Visit the Panorama of the 3 Pyramids and the Valley Temple (Mummification Temple).
• Visit the famous Egyptian Museum to see The Golden Treasure of King Tut.
• Visit Papyrus Institute and learn how this ancient art has been revived after thousands of years.
• Free walking in Khan El Khalili Bazar

So with a free day in Cairo does anybody have suggestions on other things to do or so?
