Giza Zoo to open its doors on Tuesdays, but tickets will be 13x the regular price: The Giza Zoo administration has decided to open its doors to select groups of visitors from schools or companies on Tuesdays — the only day each week the zoo is usually closed, Al Mal reports. The zoo will offer tickets at EGP 65 apiece, which is 13 times the regular price, and will only admit groups who schedule their visits in advance.
