I would recommend Maasai Mara over Amboseli, for two reasons one Maasai Mara is a larger reserve and has more animals at any time of the year.
Two Maasai Mara has better infrastructure like hotels, number of rangers etc and thus tends to be cheaper and also give you a better chance of viewing all the Big five in their natural habitat.
There is also another reason, which is that the Kenya Wildlife Service is no longer managing the Park and this has resulted in deteriorated service, this reason is however not really prominent.
If I were to advise you, go camping in Maasai Mara. It is a nice camping site.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
