It is important to take into account, especially when arriving to the Country, that there is almost an obsession with security in the airports, in order to prevent terrorist attacks. So bear in mind that you will have to undergo through many levels of controls in which even your shoes will be checked out.
Upon that, when entering in Egypt be aware that at some point you will have to deal with an in migration authority who could stop your entrance even if all your documentation is correct and all your travel journeys are set up. Best advice in this field, be respectful, and in the end understand that all the controls are in place to secure your staying.
Of course, there is always the possibility of a terrorist attack, as from time to time it appears on the news. For the time being, they do not use to happen very often, but unfortunately, that possibility exists. This is one reason more to hire the services of a travel agency.
About the documentation, you need to visit Egypt, normally with your passe port, it will be enough. Then you will have to get a tourist visa, that is not very complicated. You have two choices; the first one is to get it before traveling at the Egyptian embassy or consulates in your Country of residence. The second one, is when arriving to Egypt, which is not complicated, because you will have to fill in a form on the plane, and when arriving and passing the controls at the airports, you will have to pay for it in local currency; it is not very expensive, when writing this it costs about 35 € or about 40 USD per person. When paying, the public servant will put a stamp in your passe port that represents the receipt.
As I said, take into account that all controls are there for security reasons, and are put in place for your safety.
