On the whole, this was a decent experience.
We weren't aware the road into Masai Mara was so incredibly bumpy, and with two small children and a pensioner on board, this was information that should have been passed on to us from the start as a matter of courtesy. The car itself was very loud and the windows were quite shaky, which of course was magnified during the bumpier parts of the journey.
There was a question about money and residency status that was problematic, but eventually resolved after a few talks on the phone.
Our stay at the eco-center was pleasant, the people were friendly, and the food was lovely.
Our driver was kind and knowledgable.
Because we had two young children with us, the morning outing on the 3rd day was scrapped.
Unless a different van was available, I don't think we would ride with Safariline again.
