i take it you will just be around the cairo area?
cant guarantee alien stuff but i can tell you a few great things to visit other than the pyramids (which will make you stand and just go WOW)
list of things to do around cairo...
the museum (one whole day)
city of the dead half a day
use the other half to visit
cairo citadel
khan el
kalili best visited early evening till late night
combine it with the nearby event following.....
DEFINITELY go to this -
Wednesday and Saturday
nights at the Mausoleum of Al-Ghouri -sufi dancers its free but get there early because it will be packed and and they have to turn people away
often. it truly is one of the most spectacular things you will see. ask around to see where the sufis currently are performing as im not sure if the
renovations are finished yet.
when you are hungry - look for the LUX eating place near the museum (ask around) & try KUSHARI.
Egyptians are a wonderful people with a great sense of humour but some can be persistent in getting you into their shops.
also, if you have a special female you would like to get a present for - visit on of their perfume shops (look for the ornamental glass perfume
bottles in the windows) - it is the best perfume in the world an a tiny amount will last you for years
and above all - enjoy yourself because it is a beautiful country with fantastic people
