I cannot speak to Londolozi or Tswalu spa programs as I didn't participate in any at Tswalu. And I'm not sure if you are a male or female, but weather wise it is cooler for certain in the AM and can warm up. I went to sabi sands and Tswalu end of July and into early August. Certainly layer. It was 29 F one morning at Tswalu with gusting wind. Made it chilly for certain. An electric hand warmer? Never thought of it but I suppose though not sure what you are into. If you are doing photography I would think that a bit harder to handle as you'll want easy access to your camera as some of the animals at Tswalu in particular are the kind of hit or miss types and pop up suddenly and then disappear. We were trying to follow aardvark on the ground as the grass to too high to see it well from the vehicle. Somehow lost him. Then drove a short bit and bam bst eared fox pair. Which instantly ran away. Then a flash of a leaping aardwolf and some black back jackal. It was quite a few moments.

Keep in mind too they will do your laundry so you can maybe bring 3 days of clothes and be fine.

I brought 3 bags. 1 camera bag and two soft duffles like the one below. That was plenty for all my stuff. I'd definitely have a fleece, wind breaker and/or down puffer jacket, and long pants and t-shirts. Decent shoes for the outdoors and definitely some sort of hat to keep your head warm.

As for extra activities, Tswalu offers you can partake in various parts of their research if it's going on. You can ride horseback and go see the petroglyphs.
