I'll make an example with made up numbers, just to try and explain what the issue is.
Let's say CCV has 4 millions total points and that in 2017, 2 millions points were sold
To use round numbers, let's say the total Mousekeeping costs for the whole resort where $8 millions. Since half of the resort was sold, $4 millions were paid by
DVC on the points they retain and $4 millions by members. So for each point sold at the resort, owners have paid $2 for the Mousekeeping component.
Now let's say in 2018 the resort was 75% sold, 3 millions points were sold. Mousekeeping costs increased slightly to $8.4 million (a 5% increase). Now owners would have to pay 3/4 of the total costs, so the total per point in 2018 was:
(8,400,000 * 3/4) / 3,000,000 = $2.1 per point. So a 5% total increase in Mousekeeping expenses caused a 5% increase in the mousekeeping component of MF per point. As expected. The fact that more points split the total amount doesn't cause a discount, because a bigger share of the total costs are paid by members.
Now in 2019 budget, a 30% increase in mousekeeping costs is coming at all resorts.
We would expect the 8.4 million 2018 budget will increase to $10.92 millions. In 2019 CCV will sell out so the whole expenses will be paid by members. What we would expect is that the mousekeeping component of MF would be $2.73 per point ($10.92 millions / 4 millions). Instead the mousekeeping component in 2019 remains almost unchanged. Why is this happening?
We do not know.
