If you're going on a safari in a Third World country, you don't want to do it cheap. Don't get stuck in the bush with a guy who doesn't have a cell phone. You have to be concerned with a safe, quality vacation.

See how much time the agency (spends getting) to know you and your vacation plans. See if they ask about your travel history or what you expect. The more they try to get to know about you, the better vacation and relationship you'll get.
