You would probably get a better response to this sort of a poll if you set some guidelines.
For example, those who fly vs. drive will spend hundreds more per person just on transportation.
Many
DVC owners purchase Annual Passes as their park admission. If I can get 3 trips out of an AP, then my incremental cost per trip is much lower than someone who purchases a discounted Park Hopper for their stay. Believe it or not, there are even DVC owners who can spend a week at their resort and not even go into the parks.
Dining: Some people eat many meals in their rooms since all DVC accommodations have either a full kitchen or kitchenette. Others will still splurge for WDW table service establishments during their stay.
And your comment regarding the hotel being "free" isn't entirely accurate due to the annual fees that must be paid on all DVC points.
If you are just trying to get an idea of how people spend their money, then I guess you'll get what you are looking for. The responses will vary across the spectrum.
But if you are considering a DVC purchase, you are probably better off looking at the type of vacation that YOU want to take (drive vs. fly, dine in vs. dine out, most economical park tickets) and determine YOUR cost.
