experience about camping safari in Kenya?

Anyone who tried the camping safari in Kenya could share your
experience with me? Is it very uncomfortable to sleep? Also, what
about the hygiene standard of a toilet? Any snake or spider in the
camp sites? Suppose I go to a toilet in the midnight, is it sensible
of me to do? And how would you like the camp sites in Amboseli,
Sambura and Mara Masai? Thanks in advance!
