Swala offers immaculate service and excellent food so if you are after some serious luxury this is definitely the place to go. It's a permanent tented camp that spares no expense for the sake of comfort. Having just been through a major renovation it should be at the top of its game right now. It doesn't quite have the spontaneity of some of the other small camps and feels quite a bit more formal, but service is absolutely without fault and the food is superb.
The camp itself also looks a bit bare when you first arrive; large acacia trees with little or no vegetation below the canopy, but this is probably partly because there's no shortage of game in the area in the dry season. I suspect that this may also be to encourage the leopard to go home in between raids on the birdbath, thereby reducing the chance of you treading on his tail on your way to breakfast.
One slight catch to be aware of at Swala is that as it belongs to a subsidiary of A&K, there could be times when you find yourself in a crowd where you'll feel left out if you're the only one not wearing a hat with "Jambo" splashed across it. NOT incidentally, a reason to rush out and buy one!
