Kenya
Why not get friendly on your trip by learning a few key Swahili words!
I visited prisons in Kenya in 2005 and addressed the prisoners there in regards to their human rights and court cases.
To cut the tension (which one will need in this current political climate) start your introduction with 'mambo vipi'! The prisoners loved it because they thought it was funny coming from a Mizungo (white man). Basically, it means 'whats up?', but it worked everytime and had them rolling on the ground!
Remembering enough foreign currency to get in to the country is important.
Arriving at Mombasa after an 11-hour flight and then realising you've neglected to bring enough cash (70USD, or about £40) to get past immigration can be a slightly fraught beginning to a holiday, particularly on a Sunday, and when the cash machines in the airport are broken.
Trust me, make sure you know what the tourist immigration fee will be and that you have enough spare cash on you for this.
