As an instructor I have had to deal with DAN on a number of occaisions. I have had to deal with some very serious injuries and have had the good fortune to know some of the DAN asia pacific staff personally.
Bear in mind that DAN is actually several different companies operating under the same brand name, due to the difference in the way and by whom their insurance policies are underwritten. They are not perfect, but find me a company that is perfect and I will shave my hair for charity.
A friend of mine was killed in a motorcycle accident in Thailand and DAN did everything - contacting the embassies, arranging for Mike's body to be flown home, daily calls to his mother, everything.
They are brilliant, and whilst I know for sure that people (including myself) have had problems dealing with them, I will not hear a word said against them. For research purposes, they have a very limited budget, but for insurance purposes, at least in my meagre six years of experience, I have encountered nobody better.
Plink plink goes my two dollars and for the price you pay and what you get - for sure you are in good hands. I know this for a fact.
Cheers,
C.
