They have special summer hours just for the King Tut exhibit. It opens at 9AM and last ticketed entry time is 5:30pm. You must purchase tickets online and reserve your slots. It was sold out all afternoon on Sunday. Earlier the better to avoid crowds. There is an IMAX movie that for King Tut that can be purchased as well.
I believe its 5:30. Eally morning is typically sold out first.
