Advice:
Kenya Immigration: The correct answer is "30 days"
Money: Credit cards are not widely accepted. Cash and T-checks are vital.
Kids: Always want "pens for school". Bring a few good pens and you will make lots of friends.
Safety: Watch yourself in Nai-robbery. Keep your money spread between two internal wallets. Always have "safety cash" stuffed somewhere else.
Greetings: When someone says "Karibu", Say "Asante". When someone says "Haburi", say "Nzuri"
Animals: You ain't smarter, faster, stronger or scarier. They don't fear you, and you ain't the top of the food chain. Leave the camp site at your own risk.
Trading: Want some cool souveniers? Bring a thrashed old pair of Nike shoes and a few old Ironman watches and you can write your own ticket. The vendors jones for that kind of shit and will trade even the best carvings/masks/spears/etc for them. Anything you have is tradeable, and will command a high price in the bargain. The hot trading items: shoes sunglasses, watches, socks, clothing. Bring stuff you can part with, and you will bring back some great souveniers.
Bargaining: You are getting screwed no matter how well you bargain. Start your bargaining at 1/2 of what you are willing to pay. And don't move up too fast. Show the money, and start to walk away, and chances are, you will get the deal.
Kili: Trekking pole is damn nice to have. So is a chair kit for your Thermarest. Be sure to bring a Thermarest. The pads they provide suck rocks.
Buy the "Lonely Planet Guide" to either "East Africa" or "Tanzania and Zanzibar". They are bibles for the region. They also make a trekking guide that is damn handy to have for route research.
Be generous with your guides and porters. They are doing a shit load of work and see very little of the money. For our trek, we spent a total of $1400. Tanzania took $748 of that as park fees. The tour company took another big chunk. And very little ever made it to the guys who actually do the work.
