I know, I know you have to go....when I went last in 2009, I was irked. One, the crowds inside. I felt as though I was looking at the backs of tourists the entire time, not enjoyable.
And, two, the mall downstairs for lunch--Rick Steves' recommendations are seldom wrong--but this one was a doozy--the food was incredibly inedible in the food court - to me at least- worse than the average airport. Perhaps it has improved in the 3 years since. I am not a food snob--I ate at the BHV department store and even once I think at Subway--great for ice in drinks--bad for bread.
I will make more of a point to see the pyramids alit at night. Thanks for that tip.
