This is very important as it will affect how well you enjoy the stay in Africa. Start preparing in advance. Do not wait until the last minute to do you hotel, flight and tour guide bookings. Do it months before to ensure that all is set for the trip. There are factors to consider on any African safari. The first one and the most important is the finances available. This will be the key factor as wherever you go, money is needed. You should plan well in advance to make sure you have all the cash you need. You don't want to be out of cash half way through your trip and you are forced to go back home.
Know exactly how much it will cost you for the accommodation, transport, game park fees, air flights and any other expense on the way. Shop around in order to get better rates from the tour companies or tour guides. Even hotels have different rates depending on the season and class. Do not worry so much about the class while in Africa. In fact, the lower the class, the deeper you get to feel the real life around. Another important factor to consider is the seasons. The rainy season is not a very good time to visit Africa. You will be limited as to how many places you can visit. Most places are impassable because of bad kept roads, and rivers overflowing. You will want to just stay indoors with the cold and rain.
How long do you want to stay in Africa? How many places or countries do you want to visit while around this place? Consider this too. You do not want to overstay until your visa expires. Consider also the weather conditions so as to plan on the dress code. The stability of the government of a particular country is also a factor to consider. Know the risks you are taking when going to Africa. Are you ready for it. Choose countries that are enjoying good governance and peace.
