I just did a little more research, and confirmed RCR does NOT have insurance for terrain park liability. They self-insure, same as Whistler Blackcomb and many other large resorts.
Self-insured means that instead of relying on insurance companies to pay out liability claims, the resort has their own lawyers to handle claims, and pays out any settlements directly.
If you want to confirm it for yourself, the man in charge of liability concerns for RCR resorts is named Bob Pearson.
So, again, this decision, while it obviously is fiscally motivated, has NOTHING to do with "rising insurance premiums". Just wanted to clear that up becauses it seems to be a big assumption/misconception.
Rising insurance premiums do not affect large resorts who have the financial platform to be able to self-insure. (Although they are a big issue for smaller resorts, and ski camps like HN, Momentum, etc.)
