There is so much mystery, magic and mesmerism in this country that you wouldn’t like to leave in a hurry. But you will have to leave soon because every tourist has a budgetary constraint and the visa does not permit you to stay forever.
Ideally, duration of around 20-25 days is perfect if you wish to see the whole of Egypt in great details and without having to hurry from one destination to the other. It may appear leisurely, but a near 3-week long tour is favorable for those who wish to spend a few nights in each tourist spot including the likes of Cairo, Luxor, Aswan and Alexandria.
A normal trip usually lasts for around 8-10 days. Tours to Egypt can be planned for a small budget for this duration. It would not tax your pocket and would be long enough to enable you to check out all the major attractions.
