All good answers above.
To try to make it simple, compare as best we can apples to apples. Using OKW (my home resort for which I have numbers), compare a Studio to a regular WDW resort hotel room. Using mid-season as an average, and a 7-day week (We all know a 5-day stay Sun-Thurs is MUCH cheaper yet), compare the maintenance cost increases since I purchased in 1993.
1993 7-nights = 100 pts,
.....maintenance fees = 2.56/point = $256
.....Total $256/week or average = $36.57/night
2001 7-nights = 98 pts,
.....maintenance fees = 3.13/point = $307
.....Total $307/week or average = $43.85/night
That's an increase of only $7.28/night over 8
years.
Also, in many cases, part of the maintenance fees (the real estate taxes) are deductible from income tax. In a 28% bracket, the 2000 real estate taxes of $0.69/point = $0.19/point tax deduction, which reduces the $43.85/night average to $41.20/night.
Also, the initial purchase does represent an 'investment' that has grown in value. I could have had that money in the market (who knows what it would be worth right now?), but as a
DVC membership, I could sell my points TODAY for 25% more than I paid for them. (I know this because I just bought 100 more points OKW at resale, and the resale price is going up steadily). So my original 'investment' has grown at an annualized growth of about 3%/year, not great, but not a total loss. (Keep in mind however that this would diminish to zero if you keep the points all the way to 2042, but by then, the money you saved on rooms would be much more that the total you paid)
Finally, consider what you can get besides a Studio. Use your points on a 1-BR, 2-BR etc, and considering only the point maintenance costs, you're still paying much less than standard rooms at regular WDW resorts, but getting a much more luxorous accommodation.
Last, consider the taxes on a regular WDW resort room, 11% !!
Yes, there is a very good value in owning DVC.
