In my opinion, everybody should go to Africa at least once in their lifetime. There are many good reasons.
1. It is going to be unlike anything you've ever seen before in your life. There are many extremes from the beautiful to the downright ugly.
2. Its a challenge. Any idiot can have a good time at a resort in the Caribbean, but Africa poses many challenges. It takes a real man to stand up to all of them and protect his family while they are visiting.
3. You will become a better person. Most people don't care what happens in Africa because they will never see it firsthand. Seeing the level of poverty, hunger, disease and crime causes any normal person to ask themselves what they can do to improve things for everyone.
No doubt, people thought we were crazy for going, but it was a life enriching experience. You need to be on your guard in regards to crime. You will need to be immunized against diseases. However, this kind of trip will put your mind and body to the test allowing you to emerge better than before. One final word of advice: don't just do the safari and tourist route. Go out into the towns and villages and see daily life for yourself.
That said, if anyone has any stories or advice on travelling in Africa, I'd love to hear about it. I wouldnt give up my experiences in Kenya for anything.
