Ramez BG The palace was very beautiful and also very big but it can be visited in one day. If you tend to visit this place, please notice that this palace belongs to Mohamed Ali Tawfik, the son of Khedive Tawfik, not the popular Mohamed Ali.
Heba The palace is amazing and well taken care of. There were lots to see. I went there on Friday early in the morning so there weren't many people so I enjoyed it more. But keep in mind they ask you to leave during the prayer time, but you can enter once they finish, but only on Fridays.
Ahmed Mashaal The palace looks very modern. We enjoyed a tour here. Lots of rooms to see and the mosque is beautiful. Lots of animals were hunted also. The royal rooms are full of great Ottoman architecture, Moroccan architecture, and other architectures from around the world. You can purchase drinks here and snacks. Tour takes about 1hr to 1.5hrs and we picked up a tour guide inside after buying tickets.
Leyla Norris Nice place to spend a couple of hours. Unfortunately, most areas were closed when we visited in May, and the ticket office did not warn us. There were blocks everywhere in the garden restricting access. As well as the usual exhibits of the second and third floor of the palace were closed (no reasons were given). The toilet in the garden was locked. Hunting museum had an attendant who was just reading some of the obvious signs or pointing at very obvious exhibits by saying what it is (for example: crocodile, camel, snake). Despite all signs having English translation the attendants in each room were aiming at tips and trying to read signs for us, following us around. I noticed the locals did not get such attention. This is a bit disappointing because these kind of museums and palaces are sometimes an attempt to avoid such unwanted attention and actually get some quiet and peace at your own pace. Parking was easy on a Saturday morning. We parked right in front of the palace on the side of the road and tipped the parking assistant.
Jacques Biggs This is a spectacular palace, rich in history and must see while in Cairo. Gardens are well maintained and the Mosque on the grounds is just as amazing. The hunting displays were not my thing.
