The best part about this place is the game reserve. The complex is located right at the game reserve, and you can book a 4 hr. safari for as little as $15 dollars (US). hot air balloon rides over the game park about $100.
If you want to relax, the pool is awesome. Also, water tobogans are the best I have ever seen. The wave pool makes waves up to 8' high, and makes you feel right at the beach.
Walk around the jungle, play golf on any of the 2 Jack Nicklaus courses, go to the local ostrich farms and markets. It is a great opportunity to immerse into the local culture.
Gamble a lot and enjoy a world-class show (such as a U-2 concert if you are in luck, the Miss World Pageant contest, and many other).
Also, great place for kids.
