Interesting analysis.... It largely makes sense, though I wonder why BRV is so high compared to others. OKW is a sprawling resort to maintain. AKV has the animals. Not sure what puts BRV so high.
Second, I don't think RVA will be THAT low in the future. Their rebate was larger than most perhaps not just because they have overestimated dues, but also the closure, and no skyliner operations, gave them a bigger than normal discount.
But I will agree that the rebate is likely an indication that dues for RVA and CCV remained a bit overestimated.
