I came here in October 2012 with a couple friends as part of a 5 night, 6 day Drakensberg trip. This was the last place we stayed, and certainly the most spectacularly situated (see the attached photo). We went on 3 beautiful hikes leaving from the huts--to Tiger Falls the afternoon of our arrival (pleasant but not impressive in the dry season), a loop encompassing Surprise Ridge and Cannibal Cave (beautiful but long), and finally the Gorge (spectacular).
Our "hut" in the upper camp was great. Although more expensive than anywhere else we stayed on our trip, our unit was very clean, roomy, and well-maintained. The kitchen was fully functional and we enjoyed the back porch grill. Even though we came during the South African spring break holiday and all huts were booked, it was very peaceful, in contrast to the large campsite in the park, which we hiked through on the way back from Cannibal Cave and which had a decided spring-break atmosphere (which could be great if that's what you're looking for, but we weren't).
You should know that if you want to day-hike the Amphitheater that this is not the ideal location from which to start--you essentially need to drive out of the park and enter from another point. However, the hikes that leave from the camp are amazing in their own right, and to be completely honest the views from the huts are so great that you would be perfectly justified if you just wanted to sit on your porch and enjoy the view (+/- the company of a few baboons).
