Hi Lion Queen,
Thanks for the reply!
On Wednesday afternoon I managed to speak with a SANParks receptionist/manageress Bhulani at the Glen Reenen Camp reception who was very helpful. She had solid info about the hide, feeding times, access and hire and very pleasant and helpful.
Suffices to say if you want access to the photographic side of the hide (where your lens is not behind a sheet of smokey glass as in the main viewing area) go to the Glen Reenen Camp reception (on the R712 just beyond the GGHNP Hotel heading toward the Basotho Cultural Village Rest Camp / Harrismith) and pay a R150-00 fee per person (max 4 @ R150-00 each or R600-00). You will then be given the key to access the photo area of the hide. As I understand it you can make use of the facility the entire day and return the key in the evening.
No electricity, no cell signal at the hide
but there is signal at the parking lot (+/- 250m from hide) in case of emergencies. There is a decent clean toilet (long drop) with TP. No running water so make sure you bring your own water or wet wipes. A spare roll of TP if you are spending the entire day at the hide would make sense
If there are physically challenged/wheelchair bound people in your party then there is another key that unlocks a boom to allow one past the railings at the parking lot for wheelchair access. The interior of the hide will cater for a wheelchair although perhaps a bit tight through the multi-door area...
I am still on the road and will update as soon as I get my pictures offloaded.
(ETA: Glen Reenen Camp details and contact numbers on this page.
