I looked into it when they began advertising it a few months ago. The park activities are only available to hotel guests and the hotel is too pricey to justify going to if you live out here.
I don't think the Cabelas/Bass Pro Shop/LL Bean/Gander Mountain vibe is going to appeal to locals. IE maybe, but not OC. Although a sun-free beach would seem very appealing to FCBs.
I actually heard about this from some midwest transplants... they're psyched. Can't imagine what the bunk bed dens/cabins will look like after a few months. Blech....
