We were rather new to camping (having only done it once before), had bought all new equipment, including what is referred to as a hotel tent (6m x 3m), and decided to spend a week of our honeymoon in KNP.
We arrived at Satara on a Monday morning, found the perfect spot and spent close to 2 hours unpacking the car and setting up camp.
We had also brought with us an electric bar fridge and a large cooler-box full of meat.
When it came to plugging in, we realised that we were more than 50m from the nearest plug point with only 20m of extension cord.
Very disgruntled, we took everything out of the tent and dragged our brand new tent across the campsite to the proximity of the plug point.
At this point we realised that we would need an adapter as these were caravan points.
(The staff at the curio shop must really have a laugh, the adapter costs roughly 3x what it costs in Joburg

).
After having set up camp a second time, we realised that there were certain disadvantages to camping under a Marula tree, but we decided to just live with the fruit falling on us.
On day 2 of our stay in KNP we realised our second (or third) mistake - never camp in soft sand at the lower end of a slope.
The heavens broke open, the tent windows were rolled up and everything from our clothing, to our pillows, to our sleeping bags was either sopping wet and/or covered in mud which had pooled around us and seeped in from under the tent.
We moved the tent a 3rd time and took everything to the laundry.
Shortly after we had put the machines on, there was a power failure.
Reluctant to leave things unattended, we went back to camp to collect a few essentials (torches and a 5l wine) and spent the rest of the night waiting for the power to return.
By this time (1am), having eaten nothing and drunk plenty, we were in no condition to sort anything out, we took our wet washing back to our tent and made do with sleeping on the bare mattress.
The next morning we used the nylon cords off of the tent to fashion a number of washlines, we must have been to talk of the camp

.
To put the cherry on the top, we found out the next morning that the plug point for that campsite did not work.
With tears in our eyes, we went to the main office and begged them to repair it, which they did within about 30 mins.
Don't get me wrong, that was my best ever trip to KNP and probably the best holiday ever!
Also a really good crash-course in camping
