I think this is the main reason you want the insurance. Also if a helicopter is involved in the rescue you might be presented with a big bill.
I'd steer well clear of the budget "normal holiday" policies. I know a little bit about this industry and basically they are too cheap to provide the level of cover they claim to. The end result of that is that some people find they can be difficult to get payouts from when a claim is made. There are even rumours that some of the companies have an automatic denial of cover at first notification.
It is well worth paying a bit extra for one of the premium products. The mountaineering ones (BMC/AAC) seem to me to provide the best level of cover.
Another reason why I always nag my friends about proper snowsports cover is the increasing trend towards litigation for injuries sustained on the slopes. Sure I know the aim is not to cause crashes and injuries on the pistes but a momentary lapse can result in a crash and injuries can be significant. If you were unlucky to cause an accident where someone sustained a serious head injury you could end up losing everything you own in the litigation that follows. So third party cover is a pretty important aspect of snowsports cover (maybe not for the OP in this case though).
