Short version: Everthing was perfect.
All the transports are well organised and safe. All the people from VIVA Safari are very friendly and try their best, to give you the best experiance. The food was great and the tented lodge at Katekani was awesome - a lot of space, refreshing privat pool and even a AC, if needed.
At all the stops during Krueger Park or the transfers you are able to pay with credit cards, only at the lodge you will need cash for drinks.
Yes, the programm is packed full, but this is the best chance to see a lot of the animals. But you can skip parts of programm if wished. The bush walk was short and very interessting and easy to do.
The first night in Tremisana lodge is outside of Kruger National Park, there for you can do game-drives on sunset and sunrise, you will have the chance to see lots of animals.
We loved the experiance and our first safari and highly recommend VIVA Safari. There are other plans and camps you can book - for us the 5 days tour and to stay at Katekani was perfect.
Side node to malaria:
During this time (end of summer - more rain) malaria risk is higher. We spoke with the employees, the don't face problems.
We were pre-caution and took the "malaria-medicine" and for sure bug spray.
