We are scheduled to take both Sunrise and Wanyama Safaris, but I have some concern about potential bumpiness. How rough is the terrain on the Sunrise Safari and what is the duration of the bumpiness? Generally what is the experience like. I know the entire safari is supposed to be about an hour. If the bumpiness lasts just for a short period of time, it may be doable. If it's too bumpy, I may need to sit out that experience as much as I'd love to participate. By definition I know is a savannah is a flat plain. So is the Wanyama Safari entirely over fairly flat terrain, or is it bumpy as well? If there is some bumpiness, can you be more specific? Thanks.
