I agree with Freddie, did the sound and light show once and it was really long with excessive periods of standing to a recording. Once was enough.

However Nefartari's tomb is an absolutely incredible experience. Do yourself a favor and book the tour at Nefartari's tomb. It is possible if that many people a day start to affect the tomb they will close it again. Grab this opportunity.

Some of these images below are mixed in with pictures from Abu Simbel a totally different temple to the tomb we are discussing here. The images with the bright colors are from the tomb.
