Yeah my point is that the actual costs are likely going to be higher for Riviera on the salary expectation because the average salary cost per day for Riviera is higher than that of all the WDW resorts; I wasn't suggesting it was artificially inflated (As an aside actual costs aren't truly known, DVC sets an estimated cost for the line items, for instance they likely don't have a final tax assessment; also Capital Reserves can be freely set since DVC owns the entire resort).
The minimum wages the resorts are working with for this year are:
January & February - $11
March through August - $12
September through December - $13
So for a hypothetical minimum wage employee at the existing DVC's is costing MF on average (2/12)*($11) + (6/12)*($12) + (4/12)*($13) = $12.17. While for Riviera it is $13 for the same hypothetical employee which if everyone was paid minimum wage (which we know isn't the case but likely the case for a majority of the positions) that is about a 7% increase in the employee costs. So as I said this explains some of the $1 difference but not all of it.
As an aside the 2020 budgets, for all resorts, will have that hypothetical minimum wage employee averaging (9/12)*($13) + (3/12)*($14) = $13.25, since the next raise is October 2020. So the current WDW resorts, excluding Riviera, should see a YOY increase of about 9%, while Riviera will see just about 2% for this line item. For comparison 2018 to 2019 saw about a 21% increase in the per hour rate for this hypothetical employee (2018 - using $10 an hour on average, 2019 - stated above).
As I stated above the tax is likely estimated on the conservative side (just like it was for CCV) since the tax assessor doesn't finalize the number until after construction is completed. If I recall correctly, this was the reason between 2017 and 2018 you saw CCV MF drop because it's tax assessment was lower than expected/budgeted. Also why you saw a lower overall increase to CCV MF between 2018 and 2019 (no where near the level of the other resorts).
