Knowing that central Florida was in a danger zone for hurricanes, I asked these same questions back in 1995 when we became members.
The explanation I was given, and I don't recall all of the details, was that Disney has so many buildings, shops and properties worldwide, that if any one property were to suffer serious damage, it could easily be re-built with the cash on hand of the overall company. That being said, Disney does have insurance on their properties as a whole, however the deductible is so high that it would never be used unless more than one building were involved, and the damages overall were significant - for example - serious damage to numerous buildings in WDW. This way the cost of the insurance is kept to a minimum. This however only affects Disney owned property, the
DVC resorts are not technically Disney property, but rather, belong to the members. As per the management agreement, Disney has an obligation to maintain insurance on the DVC properties. Disney does this by adding the properties to its own suite of insured buildings, and takes on the responsibility for all necessary repairs below the deductible limit. However, we the members pay a fee for this insurance through our membership dues (apparently this is included in the language describing what our fees are used for), and this fee is based on the going rate that is normally charged by the insurance industry.
Sounds confusing - it was to me too. That beings said - I was just happy there was insurance. I also understand their point of view - if a
Disney store in Timbuktu burns down, and that is the only tragedy in the year, then the insurance premiums paid for all properties combined would cover the re-build cost of this one store.
I was also told that liability insurance was completely separate, and covered through an independent third company.
Also - keep in mind that this was back in 1995. I don't know what has changed since then, and thankfully - until now it was never a question.
Regards!
