Provide me with a plan to spend a half-day in cairo
I would start by going to the museum of Islamic art. It's a beautiful museum with an incredible collection of Islamic art and architecture. After that, I would explore the old city and see some of the ancient sites there. And then finish off the day with a trip to the pyramids. It's a truly incredible sight and you can really get a sense of the grandeur of ancient Egypt when you stand next to those massive structures.
