Madikwe and Mateya are at the same park -- about 10-15 minutes apart -- so they're both subject to the same rules.
Sorry, Andi, I didn't mean to imply that the ac at Mateya was not reliable. Of course it was in the individual cabins. However much like Singita a good part of the public spaces are open air. It's as they should be, I think, after all you're there to see Nature! But it was hot outside. We located four vents in the floor of the main lounge and I would often stand over one of those when we were in the lounge at meals or before drives. I admit I'm a real weenie when it comes to heat.
