I'm planning a Botswana safari for next year (August 12, 2010 through August 24), and I'm looking for advice regarding the kind of travel insurance I should purchase for this trip. Here are a few key facts:

I will be using frequent flyer miles for the bulk of the flying (LAX-LHR-JNB and return), but I will have purchased tickets for JNB to Livingstone, Zambia and Maun, Botswana to JNB.

I know I need medical evacuation coverage for sure.

I don't require "cancellation for any reason" coverage, but I would like to have coverage that would cover me in the event of my own sickness or the death of a family member.

I'm sure I need trip interruption coverage as well.

I'm beginning to go through the available coverages on the Insure My Trip website, but there are lots of companies and lots of coverage options.

Any recommendations regarding insurance companies and additional coverages? Thanks very much for the help.
