Karnak at night has an
entirely different feeling. The shows are in a different
language each night, so you must adjust your schedule to
get the correct one for you. We found the Sound and Light
show very informative, if a little long.
Wear or bring a
wrap, and don't forget the insect repellant. I would also
recommend that you bring a small flashlight in case you
need to leave early.
Then, you might
like to return for a third visit after you visit the
Valley of the Kings and try to relate the various
pharaohs to the portions they built.

of Karnak on pages 288-303..
