I'm a bit late in answering this, but for anyone else who's interested, here's a couple guides/events sites I've found useful for finding things to do in Nairobi: http://www.nairobikenya.com/ - Pretty good list of user rated attractions and entertainment destinations, and an events page (http://www.nairobikenya.com/whats-going-on/events/). http://kenyabuzz.com/ - Good list of places to go and new events (http://kenyabuzz.com/whats-on/events/view-day) from all over Kenya (most listed are in Nairobi). about 7 years ago
What vaccinations do I need prior to visiting Kenya. Is there an Oral medication I need against Malaria?
I agree with the previous poster, Phil covers it pretty well. In addition to the article he links to, you may also want to consult the frequently updated Centers for Disease Control page on Kenya (http://wwwnc.cdc.gov/travel/destinations/kenya.aspx). about 7 years ago
