KwaZulu-Natal is well known for the Midlands Meander.
This route that began over 30 years ago, boasts lots of lovely country accommodation, restaurants to suit every taste and many interesting experiences. The best way to enjoy the Festival (and the area) would be to stay for 2 or 3 nights.
Staying at Fern Hill Hotel would mean you might bump into a famous writer at breakfast!
Or search Midlands Meander or N3Gateway to find something that will suit you perfectly.
