Oberoi Hotels & Resorts:Mena House: Welcome
There is a limited number of rooms available at the Mena house however. Scheherezade Imports
Tour Egypt only has 3 rooms left in their allotment. Lucy is extremely helpful and she and her staff are really dedicated to help you get the most of your trip.
The festival agency also only has a limited number of rooms; which are higher cost pyramid views or palace rooms. Other hotel options offered through the agency are the Meridian, Sofitel or Grand Pyramid. I don't know how close they are to the festival. Maybe someone here does and can post?
