The problem is that most companies won't cover the cost of points at all. You can buy coverage that will do things like lost luggage, medical, trip interruption, etc. but if you try to make a claim on the "cost" of the cruise it will frequently only repay the $95 that you paid for the reservation fee. The coverage that DVC offers is also not the best; they will insure you for $5 per point. That barely covers the cost of the dues at some resorts. At least that's what I found when I researched it.
