We stayed at Sanbona's Tilney Manor, which provides excellent accommodation and food. The reserve's scenery is beautiful and we had some great wildlife experiences, including lions, cheetah, elephants and rhinos. Although not cheap, it is value for the quality provided. In planning, note that it's over an hour from the entrance gate to Tilney Manor - longer to the other accommodation. We can't comment on Gondwana or the tented camp, other than to say that they are arguably better located in terms of getting to the main wildlife areas of the reserve. You can also arrive in time for lunch at Tilney Manor, as it's full-board. An added benefit of Sanbona is that it's on the very scenic R62 and can readily be reached by lunchtime from Cape Town. One of us uses a wheelchair, though can walk a bit. We managed at Tilney Manor, though the best disabled facilities are at Gondwana (which was fully booked). The staff were extremely helpful and accommodating.
