I have just read someone's rant about experiences with the NP booking system this year. Apparently the touchscreen booking system at the ranger stations isn't working. The campsites are showing up online as being booked, but the sites are actually sitting vacant as people have been overbooking the number of nights they need to cover for any delays or changes to their itineraries. The rangers are not taking any bookings on the ground, and some of the staff at the booking office don't even know the names of most of the National Parks on the Cape, and haven't been able to find them on their system, though that may be due to some of the parks changing names recently back to their aboriginal names.
I haven't heard of any fights over campsites yet, so lets hope the frustrations on the Cape stay focused where they belong.
