Hi Carol,
I have not heard anything from other prior WS Camp travelers regarding any foods to avoid but was told that most camps have bottled water.
The Bradt Travel Guide for Botswana is a wealth of information and I found the latest edition at our local library.
FYI, on the malaria meds..Ask for Malarone which is the latest and greatest anti-malaria med.
According to our local travel clinic, most people suffer very few side effects from it as opposed to some of the older meds.
Also, you only have to take it for seven days after leaving a malaria area.
31 days and counting...
