The OP ,Candiru, being from Wisconsin can purchase the DAN Travel insurance, where as if you live outside the US you can only sign up for DAN Dive insurance, that can look a bit like Travel/Trip Cancellation insurance as there is (some) coverage for this circumstance, but it is less all encompassing in the course of making a claim. I recommend reading this thread - which is a bit rambling but touches on some good points that we should all be aware of... starting off with if your traveling companion breaks a leg the day before travel, will my part of the trip also be covered or am I obliged to go on ahead?
DAN 'Preferred' Insurance PROBLEM
giffenk, above put in a lot on that thread, thanks for that giffenk! I rather wish there was an insurance wiki/sticky on this site to articulate the policies, coverage, terminology, geographic exclusions, etc. It is a really important topic that I think does not get enough notice.
Often go with benefits provided with credit card, if flight was paid in full with it.
I have heard good and bad stories from claims against credit cards, have you ever needed to make a claim? what was your experience?
As for staying over/spending time in Dangrida, if that is where you are embarking from, there was some dengue there several years back so be sure you take precautions.
EDIT, part of the confusion for me, is the DAN information online. For example, if you go here...

they discuss 'trip interruption/cancellation' but here...
