In the fall of every year, Disney Vacation Club publishes detailed budget statements for every resort for the coming year. These budgets detail expenses for resort services including housekeeping, maintenance and utilities. They also include property taxes and contributions to capital reserves which will ultimately be used for large scale projects like roof replacement and villa refurbishments.
Below are links to side-by-side comparisons of these resort costs for each calendar year. Note that resort-to-resort comparisons may be difficult due to differences in property size, property location, nightly point costs for each villa, resort design and a number of other factors.
